What We Do
Commercial and Multi-Family Window Replacement
Window replacement across multi-family communities, offices, and mixed-use buildings — unit-by-unit phasing with occupant notice, openings weathered-in daily, and each window flashed into the weather barrier as part of the wall system rather than caulked at it. Window replacement pairs naturally with re-siding and envelope projects, where the openings are already exposed and the integration can be built correctly once.
Window Manufacturers We Install
Safety is the part of this work we take most seriously. Every crew lead is first aid and CPR certified, every crew meets weekly on safety, and a superintendent checks each site daily against a written list. Twice a year we also invite L&I onto our job sites to look for anything we have missed.
That matters more here than in a dry climate. Around Puget Sound our crews work at height on wet scaffolding through a long gray season, and weather is a safety hazard as much as a scheduling problem.
Our safety program has been recognized nationally by the NAHB, and our record with L&I is clean — no safety inspections, no license violations, no claims against our bond. You can check that yourself under contractor license SIDEPI*008N1. More on how we work safely. See how a commercial project runs.

Commercial Window Questions
Can you replace windows in occupied buildings?
Yes — phased scheduling with notice, and no opening left exposed overnight.
Windows with the siding, or separately?
With, when possible: the flashing integration is better and the combined project costs less than two mobilizations. Separately works too; we protect the existing cladding at every opening.
What warranty applies?
The window manufacturer's warranty plus Side-Pro's 5-Year Workmanship Warranty* on the installation. *Restrictions and details apply.
Do you handle permits and inspections?
Yes. Window replacement in commercial and multi-family buildings usually requires a permit, and where the opening is altered the flashing is an inspected component. We pull the permits and coordinate inspections.
How do you handle tenant notification and access?
We give written notice ahead of each phase covering which units or suites are affected and on what days, and we coordinate access with your property manager rather than knocking on doors cold.
Can the work be phased by floor or by building?
Yes, and on occupied properties that is normally how it runs. Phasing keeps disruption contained and lets you see finished work before committing the rest of the schedule.
