GS Construction builds custom woodwork and finish carpentry in Kingsville, Leamington, Essex and Harrow: built-in shelving and media walls, window and door trim, baseboards, interior doors, stairs and railings, and one-off pieces like a bar or a bench made for one specific house.
Woodwork is the part of a house you touch and look at every day. It is also where a renovation reads as finished or not, so this page goes through the main kinds of work and the choices behind each one.

Built-ins, shelving and media walls
Built-ins turn awkward spaces into some of the most useful parts of a room: shelving around a fireplace, media walls that hide cables and equipment, custom home offices, mudroom benches with hooks and cubbies, or complete closet systems with shelves and drawers. Designed specifically for your space, they can extend from floor to ceiling and fit seamlessly into your home.
We plan each piece around your needs, combining cabinets, drawers, and open shelving to create beautiful, practical storage that feels like a natural part of the room.

Trim, baseboards and casing
Quality trim work makes all the difference in giving a room a polished, finished appearance. We install baseboards, door and window casings, crown moulding, and decorative trim to complement both traditional and modern interiors.
We take pride in precise cuts, clean joints, and attention to detail. One of our clients shared how replacing outdated wall panelling and ceiling tiles with fresh drywall and trim helped completely modernize their home.

Paint-grade or stain-grade
Choosing between painted and stained woodwork depends on the look you want to achieve. Paint-grade materials offer a smooth, clean finish, while stain-grade hardwoods such as oak, maple, and walnut highlight the natural beauty of the wood.
We help you select the right materials and finishes for your project, considering durability, appearance, and how they'll complement your home's existing style.
Interior doors
Updating your interior doors is a simple way to refresh your home's appearance and improve privacy. We install solid-core, hollow-core, pocket, and sliding barn-style doors to suit different spaces and needs.
Whether you're replacing outdated doors or creating a more functional layout, we ensure proper fitting, smooth operation, and a clean, professional finish.
Stairs and railings
Updating your stairs and railings can transform the look of your entryway or living space. We work on stair repairs, new treads, railings, and spindles, combining safety, durability, and attractive finishes.
Our customers have also highlighted our work repairing and updating basement stairs, reflecting the care and attention we bring to projects of all sizes.

One-off pieces
Sometimes the most special features in a home are custom-made. From built-in breakfast nooks and window seats to home bars and unique shelving, we create personalized pieces that make your space more functional and inviting.
Whether part of a larger renovation or a standalone project, we design each piece to complement your home's character and style.
How a built-in comes together
Every custom carpentry project begins with careful measurements and a discussion about your needs. We plan the design, materials, and finishes to ensure the finished piece fits your space and serves its purpose.
From construction and installation to the final paint or stain, we focus on precision, craftsmanship, and the finishing details that make custom woodwork look like a natural part of your home.

Custom Woodwork & Trim questions
What is the difference between paint-grade and stain-grade woodwork?
Paint-grade work uses MDF or poplar and is painted, which is smooth and stable. Stain-grade work uses hardwoods like oak, maple or walnut, where the grain shows and each board is chosen to match.
Can you build shelving around a fireplace or a TV?
Yes. Built-ins around a fireplace and media walls are planned around what they need to hold, with ventilation and cable runs for the TV and equipment.
Do you install interior doors and trim?
Yes, including new interior doors, casing, baseboards and crown moulding. In older homes the door frames are often adjusted so new doors close properly.
Which towns do you work in?
Kingsville, Leamington, Essex and Harrow, from our base on Division St N in Kingsville.
