The integrity of a home begins with the foundation.

The time is now to approach these projects, add structural value to your home and realize energy savings.

Selling a colonial home? Or, selling an old house in NH?

Are you wondering, Why isn't my house selling?

Your foundation may be the reason.

17th, 18th & 19th century colonial homes are built upon, depend upon, and will only continue upon, a good foundation.

Foundation repair is an essential part of many older New England homes - due to age, weather, lack of maintenance or an accident.  

Many of these homes are in need of major repair simply because of their age, and not only are they no longer structurally sound, but they have air flowing, and in some cases, water flowing, right through the foundation walls. Nearly all foundations in need of repair require a complete clean-out, otherwise new or surface repairs are simply a Band-Aid. The Mended Wall provides comprehensive, thorough repair and rebuild assements to ensure the longevity and integrity of your structure.

Although it may not be the most favorable spot of any colonial New England home owner to give his or her attention to, the cellar of your old home is of utmost importance to preserving the integrity and longevity of these homes and in establishing improved energy efficiency.

Andrew will work to match your existing foundation so that the integrity of your home is maintained. Repointing your old stone foundation will also decrease or eliminate the cold air from flowing into your basement, providing you with a more energy efficient home. 

The Mended Wall also provides and offers guiance on necessary excavation services during projects to ensure your foundation is in good shape going forward. Water needs to go somewhere as it runs off the room of your structure. If changing the slope of the land surrounding your foundation is a required aspect of your colonial foundation restoration project, Andrew is equipped to take care of it.

"Andrew successfully completed substantial repair work on our 18th century stone foundation. This was a major project taking some 5 weeks to complete. The foundation had large cavities, areas of undermining, and was no more than rubble in places. Andrew methodically restored the foundation excavating and rebuilding the foundation walls using in part hand selected stones he brought from off site. This was a very challenging and rugged project which Andrew tackled head on. The result was a handsome and stable foundation which enabled us to pour a concrete floor, stabilize the cellar humidity, provide structural support to carrying beams, and undertake other plumbing and electrical improvements. Andrew is a true master tradesman and undoubtedly one of the finest and hardest working stone masons in New England. For challenging stone foundation repair and restoration work, you cannot do better than Andrew Spielberger."
