Specializing in injection of cracks in poured concrete foundation walls to prevent water intrusion and protect foundation and basement. Specialize in working with Realtors, Home Inspectors and Homeowners. MHIC # 93169. Free estimates via phone. Cost effective & permanent.

"Had a 5 foot long crack in my poured-concrete basement wall. It was not leaking, but I wanted to have it sealed regardless. Alek came on a Saturday, gave me his estimate, and then repaired the wall. He was very forthcoming by explaining that the repair was not absolutely necessary if there was no leakage, but I wanted it sealed anyway. He did a top rate job and I would not hesitate to use his services again."

We’re proud of our history in the Mid-Atlantic region and proud to help our communities improve the comfort and conditions of their homes.

"No other way to put it. Install went fine. When I call, email, text for warranty service… run around at every turn. They say they will schedule right away for evaluation…didn’t happen. They say they will get it replaced right away…hasn’t happened. Regret after the sale. Xavier D and Alexis C are my two “contacts”. Unacceptable. Standing by for some ridiculous message about being sorry for the experience and to call some number that will fail to get a response. Also filing a BBB complaint."

Enterprise Contracting Services is a full service Fairfax remodeling firm. From day one, we have been providing exceptional customer service in residential remodeling through an experienced staff committed to each of our client's remodeling projects.

"The work is fine. We had two full baths remodeled. They began in late June and ended just after labor day. There were days and even weeks when no work was done at all. In fact one bathroom was demolished, and then sat for at least one week... There did not seem to be good communication among staff and each person who came to do work did not know what the other had done. One anecdote is that the electrician swore he had connected the light switch for a light in the laundry room. I was standing with the project manager and we were turning the switch on and off with no light going on while the electrician is on the phone at another job, swearing he had connected the light. The upshot of the whole fiasco was that it was not until I threatened writing to the BBB and online reviews that the owner got involved and then we were able to get to completion. Again - the work is ok. We have had to call on the 5 year warranty given to us a couple times to get small items repaired. But the lack of customer service and organization through the whole ordeal was not worth it."

"My gratitude for Residential Engineering Solutions (RES) is sky high. Matt Rudy was most kind, professional and thorough in getting to the bottom of my problem. Multiple interior cracks have slowly been growing in size along the same wall in my house on both the first and second floors. It turns out the southeast corner of the two-story addition added in October, 2013, has vulnerability to a downward gravitational pull mimicking the topography of the street I live on. There is a creek at the bottom of my street which sets up a gentle but persistent downward pull toward the creek. To stop the interior wall cracks from growing the foundation under this corner of the house needs re-enforcement. More importantly, RES has given me, in writing, proof that this problem has been identified and will be resolved (soon) before I put my house on the market, whenever that may happen. Finally, after Matt toured the interior and exterior of my house, I was reminded of one of my favorite all-time movies starring Tom Hanks and Shelly Long called The Money Pit. A classic laugh-out-loud movie from the 1980s based on home renovations that never end, working with inspectors and contractors. Matt and I shared a good laugh."

Structural Engineering questions, answered by experts

A structural engineer’s report includes a professional assessment of a property’s foundation condition, structural elements like roof trusses and floor joists, and the skeleton of the home, including studs, beams, and rafters. It will also usually include an assessment of drainage on the property and any potential issues that could arise from environmental conditions, like extreme weather in the area and even tree placement.

Because of their composite structure, cutting or drilling LVL beams can compromise their integrity. We strongly advise contacting a general contractor or structural engineer before making any alterations to LVL beams. Professionals can also answer questions about choosing between a pier and beam versus slab foundation when designing your project.

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.
