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."

"Had a great experience with Chris Kuper at Basement Detective! My basement flooded from non-stop storms and I needed a sump pump installed along with complete renovation of my basement. They were very competitive in pricing and outstanding in results. Chris even helped coordinate with the contractor doing my basement renovation after the sump was installed to make sure none of the drainage was disturbed by the new work being done. I have since weathered at least 3 large storms and can hear the sump working as needed. Very happy with the results!"

Levelift Systems was founded in 1991 by Mr. Paul Mauer. Over the next twenty-three years, Mr. Mauer developed a highly respected specialty foundation contracting company, serving the State of Maryland. Unfortunately, Mr. Mauer died tragically in 2014. Levelift Foundations, LLC was formed as a means of keeping the core of Levelift Systems together and continuing to be a leading installer and foundation designer, for the CHANCE helical pier system, in the state of Maryland. Our certified helical pier installers are trained and certified by CHANCE® and we offer both residential and commercial foundation solutions in Maryland and the surrounding areas.

"Workman took three days to shore up the foundation of this very old garage. He was polite, and did a nice job. Estimates from several providers were all over the map, since some recommended extensive work involving the use of helical piers, and installation of a new concrete block foundation. I went with more conservative repair.. It looks fine, and I hope I made the right decision."

Deska Services is a licensed professional engineering, specialty waterproofing and structural contracting company. Our range of services varies from structural engineering evaluations, design, waterproofing, structural repairs, and foundation underpinning.

"My wife and I reached out to several waterproofing/foundation repair companies and ultimately went with Deska as Dave, the on-site estimator, was the most knowledgeable, honest, and efficient when assessing our basement’s water damage. We were NOT disappointed with the quality of work. Ronald and Andy showed up on time the morning of the project after giving a heads up call ~30 minutes out. They introduced themselves and explained the project scope confirming everything Dave had itemized on the project invoice before starting any work. I poked my head in the backyard a couple of times throughout the day to see if either of them needed anything, and Ronald always took a break to explain how the work was going. He took progress pictures and answered the exhaustive questions I threw his way as this was the first waterproofing project for me. The second/last day of the project prior to finishing up, Ronald and Andy gave my wife and I an overview of everything they had done and even insisted on returning the paver stones back to their original positions since we had those dug out when calling various contractors over for their estimates. A nice little personable touch! Thank you Dave and especially Ronald and Andy for your exceptional work and professionalism during the two days. Although it’s unfortunately a premium to find trustworthy contractors especially in the waterproofing/foundation repair space, I would HIGHLY RECOMMEND these gentlemen to take care of any of your waterproofing/foundation repair needs."

"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."

Structural Engineering questions, answered by experts

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

Structural engineers typically conduct inspections during a home sale or renovation, looking for signs of structural damage in various structures throughout the building, such as load-bearing walls, joists, beams, roofing trusses, foundations, and chimneys. Some of the warning signs that structural engineers check for include:

  • Dry rot

  • Infestation

  • Shifting or cracking foundations

  • Erosion

  • Water damage

  • Sagging, shifting, or damaged walls, ceilings, or roofing support

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

Yes, unresolved damage can decrease property integrity and market value.
