Question 1

What exactly do you need built, repaired, or installed?

Accepted Answer

Custom shelving, a door replacement, trim work, and structural framing are very different jobs. Be specific about the scope — it determines whether you need a finish carpenter, a framer, or a general carpenter.

Question 2

Do you have measurements or a sketch?

Accepted Answer

Even rough dimensions help. A photo with a tape measure in frame, or a simple sketch with widths and heights, lets the carpenter quote more accurately without an in-person estimate visit.

Question 3

What material do you want?

Accepted Answer

Solid wood, plywood, MDF, composite — material choice affects cost, durability, and lead time. If you're flexible, say so; if you want a specific species like oak or walnut, mention it upfront.

Question 4

Is this structural or cosmetic?

Accepted Answer

Load-bearing work (beams, joists, wall removal) may require permits and engineering plans. Cosmetic work (shelves, trim, cabinet faces) usually doesn't. This changes both the timeline and the cost significantly.

Question 5

Will paint or stain be needed?

Accepted Answer

Some carpenters finish their work; others install raw. Clarify whether the quote should include sanding, staining, or painting — or whether you'll handle finishing separately.

Question 8

What is a Finish carpentry?

Accepted Answer

Carpentry that is visible when the project is done: trim, crown molding, baseboards, doors, cabinets. Requires precision and finish-quality work.

Question 9

What is a Rough carpentry?

Accepted Answer

Structural and framing work that is later covered: walls, floors, roof framing. Rough carpenters build the skeleton of a building.

Question 10

What is a Framing?

Accepted Answer

The structural skeleton of a building: walls, floors, roof. Framing carpenters lay out and build with lumber or engineered wood; work must meet building codes.

Question 11

What is a Crown molding?

Accepted Answer

Decorative trim where the wall meets the ceiling. Crown molding adds visual finish to a room; installation is a common finish carpentry task.

Question 12

What is a Journeyman carpenter?

Accepted Answer

A carpenter who has completed an apprenticeship (typically 3–4 years) and can work independently. Journeyman carpenters handle framing, trim, cabinetry, and general construction. Certification requirements vary by state and union.

Question 13

What is a Composite decking?

Accepted Answer

An engineered alternative to wood decking made from a mix of wood fibers and plastic polymers. Composite boards resist rot, insects, and fading better than natural wood and require almost no maintenance (no staining or sealing). However, they cost 50–100% more upfront ($6–$12 per sq ft vs $3–$6 for pressure-treated wood). Popular brands include Trex, TimberTech, and Fiberon.

Question 14

What is a Shiplap?

Accepted Answer

A type of wooden wall cladding where boards are rabbeted so they overlap and create a distinctive horizontal line pattern. Originally used for exteriors and barns, shiplap has become a popular interior accent wall treatment. Installation costs $4–$8 per square foot for materials and labor. Can be installed by a carpenter or an experienced handyman.

Question 15

What is a Pocket door?

Accepted Answer

A door that slides into a compartment built inside the adjacent wall rather than swinging on hinges. Pocket doors save valuable floor space — they require zero swing clearance, making them ideal for small bathrooms, closets, pantries, and rooms where a swinging door would block traffic flow or bump into furniture. The door rides on a top-mounted track with rollers and has no bottom rail, gliding over the floor. Installation requires building a special pocket frame within the wall cavity — this frame replaces a section of standard stud framing and cannot contain electrical, plumbing, or load-bearing elements. Retrofitting a pocket door into an existing wall is significantly more complex and expensive ($800–$2,500) than installing one during new construction ($300–$800). Common issues include: the door jumping off its track (worn rollers or bent track), difficulty latching (misaligned strike plate), rattling inside the pocket (missing bumpers), and the wall flexing when the door is pushed (inadequate framing). Repairs typically require removing the door trim to access the track and hardware. A carpenter or handyman can handle most pocket door repairs.

Question 16

What is a Egress window?

Accepted Answer

A window large enough to serve as an emergency exit, required by building code (IRC R310) in every room used for sleeping — including finished basements. Minimum size requirements: at least 5.7 square feet of clear opening area, with a minimum width of 20 inches and minimum height of 24 inches. The window sill must be no more than 44 inches above the finished floor. Basement egress windows also require a window well — an excavated area outside the foundation wall — that is at least 9 square feet with a minimum horizontal dimension of 36 inches. If the well is deeper than 44 inches, a permanently affixed ladder or steps are required. Egress windows are not optional — they are a life-safety requirement that fire departments rely on for rescue access. Adding an egress window to an existing basement typically costs $2,500–$5,000 (including cutting the foundation, installing the window well, and the window itself). A building permit is always required. This is a common requirement when finishing a basement into a bedroom, home office, or rental unit.

Question 17

What is a Hardwood refinishing?

Accepted Answer

The process of sanding down the existing finish on solid hardwood floors to bare wood, then applying new stain (optional) and protective coats of polyurethane, oil, or wax. Refinishing restores the appearance of scratched, dull, or worn floors without the cost and disruption of full replacement. A typical hardwood floor can be refinished 3–5 times over its lifespan, depending on the thickness of the wear layer (at least 3/4" thick for multiple refinishes). The process involves three main phases: sanding (using progressively finer grits from 36 to 120), staining (if changing color), and finishing (2–3 coats of polyurethane with drying time between coats). Total project time is 3–5 days for an average room, with 24–48 hours of dry time before furniture can be returned. Cost: $3–$8 per square foot, compared to $8–$14 per square foot for new hardwood installation. Dustless sanding systems have reduced but not eliminated dust — plastic sheeting over doorways is still recommended. Engineered hardwood with a thin veneer (less than 2mm) usually cannot be sanded and refinished.

Question 18

What is a Floating floor?

Accepted Answer

A flooring installation method where planks or tiles are not nailed or glued to the subfloor but instead lock together and rest on top of an underlayment pad. The floor "floats" as a single mat that can expand and contract with temperature and humidity changes. Common floating floor materials include laminate, luxury vinyl plank (LVP), and engineered hardwood. Advantages: faster installation (a 300 sq ft room in 4–8 hours), can go over many existing floor types, easier to remove if needed. Disadvantages: can sound hollow underfoot without quality underlayment, cannot be refinished (laminate/LVP), and requires expansion gaps (typically 1/4" to 3/8") around walls and fixed objects. Cost: $3–$10 per sq ft for materials plus $1–$3 per sq ft for professional installation. A carpenter or flooring specialist handles installation; the subfloor must be clean, dry, and level within 3/16" over 10 feet.

Question 19

What is a Mortise lock?

Accepted Answer

A mortise lock is a locking mechanism that fits into a rectangular pocket (called a mortise) cut into the edge of a door, rather than being surface-mounted like a cylindrical lockset. Mortise locks are the standard choice for exterior doors on older homes, commercial buildings, and high-security residential applications because they combine a latch, a deadbolt, and sometimes a secondary latch into a single, heavy-duty lock body. The lock body slides into the mortise pocket and is secured with a faceplate on the door edge and decorative trim on both sides. Mortise locks are significantly stronger than standard cylindrical locks because the lock body is housed entirely within the door stile, making them more resistant to forced entry — kick-in attacks that easily defeat a cylindrical lock often fail against a properly installed mortise set. However, mortise locks require a thicker door (minimum 1-3/4 inches) because the mortise pocket itself is typically 3/4 inch wide and 6 to 8 inches tall. Installation is more complex than a standard lockset: a carpenter or locksmith uses a drill and chisels (or a mortising jig) to create the pocket, which takes 30 to 60 minutes per door. Replacement mortise lock bodies cost $80 to $300 depending on brand and features (multi-point locking, ADA-compliant lever trim, smart-lock integration). Professional installation or replacement runs $150 to $350 per door, including fitting the lock body, aligning the strike plate, and adjusting the trim. Common issues include misaligned strike plates causing the bolt to stick, worn-out internal springs that prevent the latch from retracting, and paint buildup in the mortise pocket that binds the lock body. A skilled finish carpenter or locksmith can diagnose and repair these problems, usually for $75 to $200 per service call.

Question 20

What is a Baseboard trim?

Accepted Answer

Baseboard trim (also called baseboard molding or skirting board) is the horizontal molding installed along the bottom of interior walls where the wall meets the floor. It serves both aesthetic and functional purposes: it conceals the expansion gap between flooring and drywall (required for hardwood and laminate to expand and contract with humidity changes), protects the vulnerable bottom edge of drywall from kicks, vacuum bumps, and moisture, and provides a clean visual transition between wall and floor. Baseboards come in dozens of profiles ranging from simple flat stock (ranch or colonial style, $0.50–$1.50 per linear foot for MDF) to elaborate multi-piece assemblies with shoe molding and cap molding ($3–$8 per linear foot for solid hardwood). Standard heights are 3.25 inches for builder-grade, 5.25 inches for a more substantial look, and 7.25 inches or taller for formal or high-ceiling rooms. Material options include MDF (cheapest, paintable, swells if wet), finger-jointed pine (paintable, stable), solid hardwood (stainable, premium), and PVC (waterproof, ideal for bathrooms and laundry rooms). Professional installation runs $2–$6 per linear foot for labor depending on room complexity and number of corners. The job involves measuring, cutting miter joints at outside corners, coping joints at inside corners (preferred over mitering for a tight fit), nailing with a finish nailer, filling holes, caulking the top edge to the wall, and painting or staining. A typical 12×12 room has about 44 linear feet of baseboard. Removing and replacing baseboards is common during flooring projects — a carpenter can salvage existing baseboards if they are carefully removed with a pry bar and backing block.

Question 21

What is a Wainscoting?

Accepted Answer

Wainscoting is decorative wall paneling applied to the lower portion of an interior wall, typically covering the bottom 32–36 inches (chair-rail height). Originally designed to protect plaster walls from furniture and foot traffic, it's now primarily an aesthetic upgrade that adds architectural character to dining rooms, hallways, bathrooms, and entryways. Common styles include raised panel (formal, traditional), flat/recessed panel (transitional), beadboard (cottage, coastal), board-and-batten (modern farmhouse), and picture-frame molding (classic). Materials range from solid hardwood ($15–$30/sq ft installed) to MDF ($8–$15/sq ft installed) to PVC for wet areas like bathrooms ($10–$20/sq ft installed). Installation involves measuring, cutting panels or molding, nailing or gluing to the wall, caulking seams, and painting. A carpenter or finish carpenter typically handles installation, though handy homeowners can tackle simpler beadboard or board-and-batten styles as DIY projects.

Question 22

What is a Joist?

Accepted Answer

A horizontal structural member that spans between walls, beams, or foundations to support a floor or ceiling. Floor joists are typically 2×8, 2×10, or 2×12 dimensional lumber (or engineered I-joists or floor trusses) spaced 16 inches on center. Ceiling joists are lighter since they only support the ceiling material and attic insulation, not live loads. Joist size and spacing determine the floor's load capacity and stiffness — undersized or overspanned joists cause bouncy, squeaky floors. Never cut, notch, or drill through joists without understanding the structural implications: improperly placed holes for plumbing or wiring can dramatically weaken a joist. Sistering (bolting a new joist alongside a damaged one) is the standard repair for a cracked or sagging joist and costs $100–$300 per joist. A structural engineer should evaluate any joist that has been compromised.

Question 23

What is a Load-bearing wall?

Accepted Answer

A wall that carries weight from the structure above it — the roof, upper floors, or both — down to the foundation. Removing or modifying a load-bearing wall without proper support (a beam, header, or post system) can cause sagging floors, cracked drywall, jammed doors, and in extreme cases structural collapse. Identifying load-bearing walls requires checking the direction of floor joists (walls perpendicular to joists are typically load-bearing), locating the main beam or ridge line, and reviewing the home's blueprints if available. Exterior walls are almost always load-bearing. Interior load-bearing walls usually run parallel to the ridge of the roof and sit above the main beam in the basement. A structural engineer's evaluation ($300–$800) is strongly recommended before any wall removal. Replacing a load-bearing wall with a beam typically costs $1,500–$10,000+ depending on span length, beam material (LVL, steel, or glulam), and whether temporary shoring of the structure is needed during construction.

Question 24

What is a Sill plate?

Accepted Answer

The horizontal piece of pressure-treated lumber (typically a 2×6 or 2×8) that sits directly on top of a concrete foundation wall and serves as the transition point between the foundation and the wood framing above. The sill plate is anchored to the foundation with J-bolts or anchor bolts embedded in the concrete, spaced every 4–6 feet. A foam sill seal gasket (compressed closed-cell foam) sits between the concrete and the wood to block air infiltration and prevent moisture wicking from the concrete into the framing. The sill plate is one of the most vulnerable points in a home's structure: it's the first wood that termites reach from the soil, the first to rot if moisture management fails, and a major source of air leakage if not sealed. Signs of sill plate damage include sagging or uneven floors, cracks in interior walls near the floor line, visible rot or insect damage in the basement or crawl space, and drafts along baseboards on exterior walls. Sill plate replacement is a major structural repair ($100–$300 per linear foot) that requires temporarily supporting the framing above with hydraulic jacks.

Question 25

What is a Polyurethane finish?

Accepted Answer

A clear protective coating applied over wood surfaces — hardwood floors, deck boards, furniture, cabinets, and trim — to shield the wood from scratches, moisture, UV damage, and wear. Available in two formulations: oil-based polyurethane ($30–$70/gallon) provides a warm amber tone, excellent durability, and a thick build in fewer coats (2–3 coats), but takes 8–24 hours to dry between coats and has strong VOC fumes requiring ventilation. Water-based polyurethane ($35–$80/gallon) dries crystal clear with no yellowing over time, dries in 2–4 hours between coats, and has much lower VOC content, but requires 3–4 coats for equivalent protection and shows scratches more readily. For hardwood floor refinishing, most professionals now prefer water-based polyurethane for interior work (lower odor, faster turnaround) and oil-based for high-traffic commercial floors (greater abrasion resistance). Sheen options range from matte (flat) through satin, semi-gloss, to high-gloss. Application cost for hardwood floors: $1.50–$3.00 per square foot for sanding and 3 coats of polyurethane (professional).

Question 26

What is a Pergola?

Accepted Answer

An open-roofed outdoor structure consisting of vertical posts supporting crossbeams and an open lattice of rafters, providing partial shade for patios, decks, gardens, and walkways. Unlike a gazebo (fully roofed) or a pavilion (solid roof, open sides), a pergola's open-rafter design filters sunlight rather than blocking it entirely. Materials and costs: pressure-treated wood ($3,000–$8,000 for a 12×14 ft structure), cedar or redwood ($5,000–$12,000), vinyl/composite ($4,000–$10,000, lowest maintenance), aluminum ($6,000–$15,000, often motorized louvers). Freestanding pergolas require footings (concrete piers or post anchors) and may need a building permit depending on size and local codes — many jurisdictions require permits for structures over 120 sq ft or taller than 10 feet. Attached pergolas must be properly ledger-mounted to the house with flashing to prevent water intrusion. Add-ons: retractable canopy shade ($500–$2,000), string lights or integrated LED lighting ($200–$800), climbing plants on the lattice (wisteria, grapevine, jasmine). A carpenter or general contractor typically builds custom pergolas; kit pergolas are available from $1,500–$5,000 for DIY assembly.

Question 27

What is a French cleat?

Accepted Answer

A wall-mounting system consisting of two interlocking pieces of wood or metal, each beveled at a 45-degree angle — one strip fastened to the wall (screwed into studs), the other attached to the back of a cabinet, shelf, or heavy object. The angled cuts hook together under gravity, distributing weight evenly and allowing easy repositioning. A single 3/4-inch plywood cleat screwed into two studs can hold 75–200 lb; aluminum extruded cleats (French Cleat Rail by Hangman, Wall Control) support 200–300 lb per linear foot. Material cost: $3–$8 per linear foot for shop-made plywood cleats, $10–$25/ft for commercial metal systems. Professional installation: $150–$400 for a full garage or workshop wall (8–16 ft of rail). French cleats are the preferred method for hanging heavy wall cabinets in garages, tool walls, and TV mounts in commercial settings because they self-level, can be reconfigured without new holes, and handle shear loads better than standard picture hooks or toggle bolts.
