Home Addition & Remodeling Contractor | Hartford County, CT

Lagace Construction serves homeowners throughout Hartford County, CT — from the dense suburbs of West Hartford and Manchester to the rural communities of Marlborough and Bloomfield. Based in neighboring Andover, CT, we provide home additions, kitchen and bathroom remodels, garage construction, and new builds across fifteen Hartford County towns.

Hartford County is Connecticut’s most populous county, and its housing stock reflects that diversity — post-war ranches, historic colonials, mid-century splits, and newer executive homes all exist side by side. We’ve built and remodeled across this entire spectrum: matching craftsman detailing on West Hartford colonials, building substantial family room additions on Glastonbury colonials, and converting Enfield ranches to two-story homes. Whatever the scope, we bring the same hands-on crew and clear pricing.
