"Excellent Work on My Fieldstone Foundation! I couldn't be happier with the work Four Seasons Foundation Repair did on my fieldstone foundation. They did a great job, and I'm extremely pleased with the results. Their workmanship and attention to detail really showed. It's not easy working with older fieldstone foundations, but they handled the job beautifully. I highly recommend Four Seasons Foundation Repair to anyone looking for quality foundation work. Thank you for a job well done!"

"When we purchased our New England 1910 home and found East Coast Construction and Development Inc. to renovate, it was the best experience ever. They delivered everything that they promised and more! Quality and reliability, communication and patience with my ever changing mind! We had the home remodel throughout several rooms. They installed Stainless steel appliances, quartz counter top in kitchen (total gut job!) Installed vinyl replacement windows, engineered flooring, updated bathrooms, tiled shower, brand new carpet and fresh interior paint. We also had a pine wall installed! Came out perfect! I couldn’t be more thankful to East Coast Construction and Development Inc. for all the work! East Coast Construction and Development Inc."

"We needed an outside wall replaced due to rot. JC responded to our inquiry quickly and was able to put us in the schedule quickly. They did a fantastic job replacing the wall, installing a sliding glass door and new windows. In addition, the living room was painted an a gutter was installed surrounding our deck. Communication was great. I would highly recommend them."

Retaining Wall Installers FAQs, answered by experts

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.

Even if you think you know how to build a retaining wall theoretically, doing the actual work is a completely different story. There are lots of nuances in building retaining walls, and the slightest oversight can compromise their integrity. Therefore, we recommend you hire a pro to build, repair, or replace retaining walls.

Costs depend on material type, labor rates, and additional features like decorative finishes or reinforcement.

If you don’t backfill a retaining wall—either at all or adequately enough—the wall won’t drain well, and water will be able to pass through it. Poor drainage will lead to a warped wall or a buildup of hydrostatic pressure, which can eventually collapse your retaining wall. If you have particularly sloped land, consult a structural engineer to ensure your hardscaping is adding value to your home.
