About Foundation Work

The most important part of your house is the foundation, and we give it the serious attention it deserves. Stonehenge Masonry offers a LIFETIME warranty on full foundation restorations. We work on all foundation types, including concrete foundations but with special talent at restoring old stone foundations. A stone foundation is designed to last forever with proper maintenance, needing only a full restoration every 100 years or so. 

Foundations are made of two walls, or “wythes,” of stone, each with a finished face facing outside and inside respectively. Between the 2 wythes is a core filled with grout. Generally, the outside of the foundation is the most important aspect to maintain, since it acts as the main barrier against water penetration and it supports the exterior brickwork. The interior walls are generally of lower quality rubble stone since they are not being battered by the elements, but restoring them can be key to solving water infiltration and moisture issues.

The most common foundation job is exterior repointing. We cut and vacuum all existing joints, re-lay any loose stones, and replace damaged stones, as required. We give the entire wall a deep pointing to completely fill the voids, and we will then apply a final pointing with the original finish.

Our foundations services include:




Stone resetting and re-laying


Back pointing and grouting


Stone repair and replacement


Concrete repair and parging

Wonderful job and good crew. My 110 year old house in Westboro had crumbling brick and many novice patch jobs over the years. Stonehenge rebuilt the bottom 2 feet of brick. It looks great and matches well with the old brick. Thank you Stonehenge! You exceeded my expectations and hopes.

Stonehenge did a great job installing a stone mantelpiece for us. The installer took great care to do an A+ job, even going so far as to use a brand new drop sheet to keep the worksite clean. The end result looks really nice. We received prompt and courteous help from their office throughout the process. I recommend them without reservation 🙂

A 5 star is warranted for Stonehenge. Our job was small however important. They were totally professional and prompt with their replies and with the service. Looking at the job after completion you can hardly tell anything had to be fixed in the first place. Most important is after they had left you couldn't even tell they had been there.Highly recommend.

Another fine job by Stonehenge. They made a special effort to work our small project into this year's outdoor season and did an expert job of blending existing sandstone with new material obtained at Cohen and Cohen. Their work estimate was right on. Can't think of a better choice for natural stone work.

Super professional and organized. Very easy to deal with, I was impressed with how quickly I got a quote (and the price was very reasonable). The office staff is nice and prompt with issuing receipts and booking work etc. The guy who did the work was professional and explained things to me clearly, and did an excellent job. I would not hesitate to recommend this company and I would absolutely return to them in the future.
