General Contractor in Grimsby, ON

An addition or a finished basement rarely involves just one set of hands. A structural engineer may need to sign off on a beam calculation, a municipality has to review and approve the permit application, and several different trades need to work in a specific sequence so that framing, plumbing, and electrical don't conflict with each other along the way. When those pieces are managed by separate parties instead of one accountable plan, something inevitably falls between two people's areas of responsibility, whether that's a missed inspection window or a detail that never made it from the engineer's drawing to the framer's layout on site. Holding the estimate, the consultants, and every trade under a single point of responsibility is what keeps a project like this from losing pieces along the way, even as the scope grows more complex over time.


Sitting directly against the Niagara Escarpment, with the Bruce Trail running along the ridge above town, much of the surrounding land here was historically farmed as part of the Niagara fruit belt. That combination of escarpment-adjacent terrain and long cultivated agricultural soil means lot conditions can vary noticeably from one property to the next, even along the same street.


We are Integrated Contracting, and we bring a reliable general contractor's 18+ years of work to every Grimsby, ON project, handling everything from Structural Repairs & Rehabilitation to Home Additions and Basement Developments. Before finalizing a plan, we investigate the actual conditions rather than assuming, and every project runs under one contract covering the drawings, permits, consultants, and trades involved from the very first estimate through to the final inspection.

About Grimsby, ON

Grimsby was founded in 1790 by United Empire Loyalists and was incorporated as a village in 1876 before becoming a town in 1922. In 1970, Grimsby merged with the Township of North Grimsby to form the town's current boundaries, and the 2021 census recorded a population of 28,883 residents.

The town sits on the shore of Lake Ontario, bounded to the south by the Niagara Escarpment, and its long agricultural history as part of the fruit growing region has since given way to wineries and distilleries that make Grimsby a gateway into the broader Niagara wine region. A stretch of the QEW runs directly through town, connecting three separate interchanges along its route.


Landmarks include the Grimsby Museum and the historic St. Andrew's Anglican Church, completed in 1825, along with the brightly painted lakeshore cottages known locally as the Gingerbread Houses. Winters bring an average of 139.8 centimetres of snowfall each year, with temperatures typically ranging from about negative 16 to 4 degrees Celsius through the coldest months.

Grading and Drainage Planning for a Grimsby Addition or Basement Development

A lot's slope and soil composition determine where water goes once it rains, and on escarpment-adjacent land, that pattern can differ significantly from a flat, inland property. Grading that directs water away from a foundation and drainage planned around how a specific lot actually behaves are both assessed before an addition or basement development is designed rather than assumed.


Soil that was historically cultivated for fruit orchards can also compact and drain differently than soil that has never been farmed, which affects how a foundation footing is engineered and how a basement's waterproofing is specified. None of that makes a Grimsby lot harder to build on; it simply means the site itself needs to be read correctly before drawings are finalized.


Skipping that assessment, rather than the slope or soil itself, is what creates problems on a project like this. Sending a plan to permit before the grading and drainage are properly understood is what leads to rework later, not the land the home sits on.

Site Assessment Before Design on a Grimsby Renovation Project

Most established general contractors begin a project with a site assessment rather than jumping directly to drawings. That typically includes reviewing the lot's grade, checking for existing drainage issues, and opening up any area of the structure that a renovation will directly affect, so that the eventual quote reflects real, verified conditions rather than a general assumption.


For projects that involve a structural change, an engineer generally reviews the specific beam, footing, or wall in question and provides calculations that a municipality's permit department can approve. Coordinating that review alongside the rest of the drawings, instead of treating it as a separate track, typically keeps the permit process moving in step with the rest of the design.


Once a permit is approved and work begins, sequencing the trades so that framing, plumbing, and electrical don't conflict is standard project management practice on a multi-trade job. Written updates on budget and progress, issued on a regular basis, generally give everyone involved a shared, current picture of where a project stands relative to the original estimate.

Why Grimsby Residents Trust Integrated Contracting

Being an experienced general contractor in Grimsby, ON has meant learning how differently one lot on the escarpment can behave compared to the next, and building that assessment into every plan long before drawings are finalized. Chris Zavarise, the company's owner, still walks each Grimsby project personally rather than stepping back once a contract begins.


Every project runs under a single contract covering the estimate, drawings, permits, consultants, and trades, which means Grimsby property owners have one accountable party managing the whole scope rather than juggling separate agreements with separate crews. That structure matters most once site conditions turn out to differ from what was originally assumed at the outset, since one party already owns the adjustment.


Canadian-owned and operated, licensed, and insured, and built around current Ontario building codes, Integrated Contracting brings over 18 years of general contracting work to Structural Repairs & Rehabilitation, Home Additions, and every other service on offer throughout Grimsby.

What our customers say

frequently asked questions

Does a sloped or escarpment-adjacent lot change how a basement development gets planned?

It can. Grading and drainage patterns differ from one lot to the next near the escarpment, so we assess how a specific property handles water before finalizing a basement plan. That step shapes decisions like waterproofing and where a sump system gets positioned.



What's the first step when a business wants to renovate an existing commercial space?

The first step is a walk-through of the space so we can see the actual conditions firsthand, followed by a conversation about how the business plans to use the renovated area. From there, we put together drawings and a scope before any work begins.



How does a Restaurant Project differ from a standard retail fit-out in general scope?

A Restaurant Project typically involves more specialized systems, such as kitchen ventilation and additional plumbing, along with front-of-house finishes for dining. A retail fit out usually focuses more on open floor layout, lighting, and storefront presentation.



Is Integrated Contracting licensed and insured for both residential and commercial work?

Yes. Integrated Contracting is licensed and insured, and we work to current Ontario building codes across every project type we take on, from a small residential upgrade to a full commercial buildout or an institutional building.



Can a project include more than one service at once, like a Home Addition combined with a Basement Development?

Yes, projects like that are common. Since every service runs under the same single contract, combining a Home Addition with a Basement Development just means coordinating both scopes together rather than treating them as two separate jobs.



What's an example of a project that would fall under Accessibility Upgrades rather than a general Residential Renovation?

Widening a doorway, adding grab bars, or installing a stair lift are typically Accessibility Upgrades, since they target mobility specifically rather than the room's overall design. A general Residential Renovation is broader, reworking layout and finishes without that specific focus.



Does Integrated Contracting provide design input for a Home Addition, or only handle the construction phase?

We provide design input as part of the process, working through layout and how the addition connects to the existing home before drawings go to permit. Construction follows that same plan, so the design and building phases stay connected under one contract. Does Integrated Contracting arrange the consultants a project needs, such as a structural engineer, or does the client have to find those separately? We arrange the consultants a project requires as part of our contract, rather than leaving clients to source and manage them separately. That keeps the engineer's input, the drawings, and the construction schedule coordinated under one plan.
