Andover-based, building across Coventry for 15+ years.
We are a family-run, design-build construction firm with deep roots in Tolland County. From our shop on Long Hill Road in Andover, our crews work Coventry projects nearly every week — additions, kitchens, baths, garages, and ADUs.
Every Lagace project comes with a fixed scope, transparent pricing, a single point of contact, and a real schedule. No subcontractor chaos, no surprise change orders, no missing weeks.
Coventry building has its own quirks. We know them.
Coventry's mix of lakefront properties, older Cape and Colonial housing stock, well-and-septic systems, and stricter zoning around Coventry Lake means a "just like the last project" approach does not work here. Permits, setbacks, and septic capacity all need to be verified up front.
We pull permits with the Coventry Building Department, coordinate with the local health district on septic-impacting additions, and design around the realities of older foundations, hand-dug wells, and tight rural lots.
Home additions, ADUs, kitchens, and baths and full-service remodeling for Coventry homeowners.
Home Additions & Second-Story Expansions
First-floor bump-outs, full second-story additions, garage-to-living conversions, and master-suite additions. Engineered, permitted, and weather-tight on schedule.
ADUs & In-Law Suites
Detached ADUs and attached in-law suites under Connecticut's ADU statute. We handle zoning, septic capacity reviews, and the new state-level approval pathway.
Kitchen & Bath Remodeling
Full design-build kitchens and baths — layout redesign, cabinetry, countertops, tile, plumbing, electrical, and finishes. Most kitchens complete in 6–10 weeks.
A design-build firm built on craftsmanship, communication, and on-time delivery.
Real craftsmanship from a small in-house team.
Our lead carpenters have 10–25 years on the tools. We do not rotate strangers through your home each week — the same crew starts and finishes your project.
We actually live and work near Coventry.
Headquartered in Andover, with active job sites in Coventry, Hebron, Bolton, Mansfield, and Tolland. We know the inspectors, the suppliers, and the soil.
Schedules we hit, budgets we stand behind.
You get a written schedule, a fixed-price contract, and weekly progress updates. If we say 12 weeks, we mean 12 weeks — barring weather and homeowner changes, which we document upfront.
Thinking about a Coventry addition, ADU, or remodel?
We will visit your home, walk the project with you, and give you a clear written estimate within 5–7 business days. No high-pressure sales, no junk fees.
