Scope yours with Baily in SeattleAsk Baily about your Seattle remodel and you will not be passed around. Seattle is our Pacific Northwest market because the Puget Sound residential renovation economy runs through the single most demanding permit review regime of any major American city — Seattle Department of Construction and Inspections (SDCI) plan review routinely takes eight to sixteen weeks even on straightforward residential scopes — and the cost of routing homeowners through a twelve-contractor aggregator is measurable in months of project delay. Angi and its peers will happily sell your Seattle job to a panel of local builders. What Baily does is different. We introduce one Baily-vetted Seattle builder who already holds active Washington Department of Labor and Industries (L&I) Registered Contractor status, who has documented SDCI plan-review project experience, who understands Cascadia seismic requirements on older stock, and who has delivered shoreline-management work along Puget Sound or Lake Washington frontage. One pro per homeowner, from first message through Certificate of Occupancy. No quote spray, no twelve strangers, no re-explaining your project to a new contractor every month while SDCI holds the plans.
