Basement Insulation in New England & Greater Boston
- Rim Joist Insulation: The band of wood where the floor framing meets the foundation is a major air leak — spray foam seals it completely.
- Foundation Wall Insulation: Closed-cell spray foam or rigid foam board applied to basement walls for thermal performance and moisture resistance.
- Slab Insulation: For unfinished slabs, rigid insulation below or above the concrete dramatically improves comfort.
- Basement Moisture Control: Proper insulation combined with vapor barriers and air sealing reduces humidity and prevents mold in Hudson-area basements.
- Finished Basement Preparation: We prepare all surfaces for insulation before you add drywall and finish — the correct sequence for a dry, comfortable space.
- Combination Approach: For maximum performance, we often combine rim joist spray foam with wall insulation and air sealing in a single project.
