Harrow sits between Kingsville and Amherstburg in the Town of Essex, and Colchester runs along the Lake Erie shore just south of it. GS Construction, based on Division St N in Kingsville, renovates and builds for homeowners in Harrow and Colchester as part of its work across Kingsville, Leamington and Essex.
The work in Harrow covers the yard and the house alike: the deck, the fence and the shed outside, and the bathroom, the kitchen and the extra room inside.

Fences, sheds and backyard builds
Bigger yards need fences that hold a straight line over a long run and stay plumb through the winters. Posts go in first and deeper than the frost reaches, and on a slope the fence either steps down in level sections or follows the ground in one smooth line. Homeowners have described GS Construction building a fence on sloped land and through a flower bed without damaging it.
The same crew builds the structures that go with a yard: sheds, pergolas, gazebos and add-ons such as a chicken coop run built on to an existing shed. A new fence takes about a week and carries a 10-year warranty.

Decks, pools and covered outdoor rooms
A deck in Harrow is often more than a landing off the back door: a deck around an above-ground pool, a covered pergola deck that can be used through the summer heat, or a raised deck with wide stairs down to the lawn. Each starts with where the sun falls in the afternoon and which door you carry the food out of.
Composite boards need almost no upkeep beyond a spring wash. Cedar and pressure-treated wood bring the look of real wood and take a coat of stain every two to three years. A new deck takes about a week, and decks carry a 10-year warranty.

Bathrooms
Most bathroom projects are one of three sizes: a refresh of the surfaces with the layout kept, a full renovation down to the studs, or a layout change such as a tub turned into a walk-in shower. A full bathroom takes about two weeks.
The details are where a bathroom looks finished or not: a niche lined up with the tile, grout lines that meet at the corners, trim cut tight to the casing. Attention to detail is the thing homeowners mention most often in GS Construction's Google reviews. Bathrooms carry a 5-year warranty.

Kitchens and custom woodwork
A kitchen can change completely without moving the sink or the range: new cabinets, a light counter, plank flooring and new lighting take a dated room to a bright one in the same footprint. When the layout does change, the island, the seating and the walkways are planned first.
Custom woodwork finishes the job: a wet bar with its own counter, built-in shelving around a fireplace, trim and baseboards through the house. Kitchens carry a 5-year warranty.
Flooring and tile
Flooring and tile often come with a bigger project and sometimes stand on their own: vinyl plank through a main floor, tile in a bathroom or an entry, a pebble shower floor. The work starts underneath, with a subfloor that is flat and solid, because every floor shows what is below it.
Tile layout is planned before the first piece goes down, so the cuts land at the edges and the lines run straight from room to room.

Additions and how a project runs
For more room inside, an addition at the back or the side of the house, a sunroom or a suite for a parent takes about two months of construction for a full addition. The new space is closed in before the existing wall is opened.
Every project starts with a visit to your home. The quote follows the visit, before any work starts. GS Construction is fully insured and covered by WSIB, takes care of the permit when a project needs one, and leaves the site clean at the end of each day.
