Rated 5/5
We work with custom builders, designers, and homeowners deep in the build process. Detailed specs, on-site coordination, and an installation standard that matches the rest of the project.

We’ve partnered with:
Most window and door suppliers are sales-led. We are specifying-led. The difference shows on the punch list.
Other Companies
Sales-led specs
Spec written backwards from what is in stock or on margin, not from the wall assembly or the climate.
Site-coordination by email
Late drawings, missed handoffs, framers waiting on confirmations they should already have.
Install treated as a line item
Volume crews, fast moves, problems handed back to the builder.
With Rideau
Specs that respect the design
We specify around the architect's drawings, the wall assembly, and the climate. Not around inventory.
Real coordination
One point of contact from spec to install. Drawings reviewed, openings confirmed, deliveries sequenced to the build.
Installation as the product
The same Rideau install standard scaled to a build site. Tidy, documented, on schedule.
A short list of the things that quietly determine whether the windows and doors phase runs smoothly.
Specifying support from day one
We sit with the architect, the builder, or the homeowner early enough to influence the wall assembly, not just the window.
Drawing reviewed properly
Rough openings, head heights, sightlines, mulled assemblies. We catch the conflicts before they cost.
Preformance documented
U-values, SHGC, and air leakage figures laid out clearly, ready for inspection and rebate paperwork.
Coordinated deliveries
Sequenced to the build, not to a warehouse calendar. Site contact known, logistics confirmed.
A tidy install standard
Trades on the site after us should not be cleaning up behind us. They are not.
One relationship. All phases.
The same Rideau lead through spec, install, and any future work the homeowner wants. y so it sounds and feels right.

01
Project conversation
We sit down with the builder, designer, or owner; go through the drawings, the wall assembly, and the intent of the project. Early enough to influence what happens at the rough opening — not after the framing is locked and changes cost three times as much. We ask the questions a specifying partner should ask.
Specification
We draft a complete window and door schedule: performance figures, finish selections, hardware, and procurement timeline. Reviewed with the project team before sign-off. Nothing is ordered without full alignment. Every detail is traceable.

03
Coordination and install
Deliveries sequenced to the build schedule, not to a warehouse calendar. The same Rideau install standard we bring to a residential replacement — tidy, documented, on schedule. Full handoff to the project team and the homeowner. The windows and doors phase closes cleanly, on the first try.
At what stage of the build should we bring Rideau in?
As early as possible, ideally before framing is locked. The sooner we review the drawings, the more we can influence the rough opening sizes, head heights, and wall assembly details that determine how the windows and doors will actually perform. Changes after framing are expensive. Changes at the drawing stage cost nothing.
Do you work directly with builders and designers, or only with homeowners?
Both. We work with custom builders, architects, interior designers, and homeowners who are managing their own build. The engagement looks different depending on who is leading the project, but our role is the same: one point of contact from spec to install, with full accountability for how the windows and doors phase closes. We are comfortable sitting in a project meeting with a builder and being useful in that room.
Can you spec around an architect's drawings?
Yes, and that is how we prefer to work. We review the drawings, identify any conflicts between the design intent and the rough opening dimensions, flag concerns before they reach the site, and build a window and door schedule that maps directly to the architectural package. Nothing is ordered without review from the project team, and every decision is traceable back to the original drawings.
How do deliveries work on an active build site?
We sequence deliveries to the build schedule, not to a warehouse calendar. That means we confirm the site contact, coordinate with the foreman, and stage product when the framing is actually ready to receive it — not weeks early when it will sit on-site and get damaged. We have one point of contact throughout, and they are reachable when something shifts on the build schedule.
What documentation do you provide for inspections and rebates?
We provide full performance documentation for every window and door we install: U-values, Solar Heat Gain Coefficient, air leakage ratings, and Energy Star certification where applicable. This is prepared in advance and ready for inspectors and for any rebate applications under programs like the Canada Greener Homes Grant. We make sure the paperwork is correct the first time.
Who is our point of contact through the whole project?
One person, start to finish. The Rideau lead who reviews your drawings is the same person coordinating deliveries and present at install. There are no handoffs between a sales team, a project manager, and a subcontracted crew. One relationship covers specifying, procurement, on-site coordination, installation, and any questions after the build closes.
