Exterior Waterproofing Experts is a Class A General Contractor in the state of Virginia since 1997. Our service protects your home against wet basements, water leaks, flooding, water seepage, foundation leaking, and wall seepage. We have been doing subcontract grading and drainage work for many years. We have completed many waterproofing contracts for residents of Fairfax County, including: Fairfax, Alexandria, Arlington, McLean, Great Falls, Potomac, and Vienna, Virginia (VA). We are now offering to work directly for clients, passing the savings on to the homeowners. It is our belief that water problems are best solved from the outside before water gets into your home.

"My basement had mold and evidence of water damage in July/August, and I was referred to Exterior Waterproofing Experts. The majority of the mold was on the side of my house, but the salesperson made a strong pitch about the need to waterproof the front of my home by digging up the garden down to the foundation. My wife was largely convinced, so we went ahead with the $8000 project. Six months later, the insulation behind the waterproofed front of the house is sopping wet. When the salesperson came back to my home to take a look, his explanation was that the water probably came up through the floor. His words were along the lines of "99% of the time the water comes up through the front." At this point, I feel like I have an expensive solution to a problem I didn't really have."

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!"

Richard's Tree Service does both residential and commercial work. Since 1996, our tree company has continued to provide the community with quality work done by people who care about there clients. Richard and Rock Berube have more than 55 years of combined industry experience. Richard's Tree Service is family owned and operated business. Our office is professionally staffed. We have established ongoing relationships with our clients and have a substantial amount of repeat business. We are bonded and insured!

"Richards tree service came and did a $500 tree trimming job and I know have $1200 in damages to my backyard. On Nov 28th. 2020 “Richard Tree Service” came to my house to trim a tree in the backyard. They trimmed the tree with a fence and raised bed directly under the tree branches. Large branches were not cut in small chunks, but large heavy branches were cut and fell 20+ feet. While the branches were falling on the fence, a post in the center of the fence broke as well as the raised bed. The fence is now leaning because of the broken post. I reached out to Richards Tree Service many times from Nov 29th, through Dec 9th and they mostly avoided my calls at that time. After Dec 9th they reached out and said they will not do anything to mitigate this issue. The fence needs to be repaired. They say they will not repair anything. I got a quote for the repair and its over $1200 because there is a nice raise bed also attached to the post. They have since said that the post has mold and was compromised before they trimmed. All the other posts are not compromised and have no mold, and it is not easy to see the raised bed wood. I also don’t agree that the broken post is moldy, its broken. They want me to pay the $1200 to have someone repair the fence and bed. They also stated they wanted to be there when I have MY fence repair person come pay… I don’t have $1200 to dish out just for them to later say “still not paying”. They have insurance but refuse to use it. I have tried contacting the insurance information but their provider never responds. Also, even with all of this happening I tried to pay my bill. Apparently to pay they wanted me to take down someone’s wife’s phone number to give her my credit card. I get it that this is a small business person who may be just contracted through Richards tree service, but its still unprofessional. I do not feel comfortable giving someone’s wife my credit card and will be trying to pay a different way. I also had someone else come out to look at their job. They left cut branches just sticking out. I am not sure why they didn’t cut from the base of other branches or the trunk. I am pretty sure those random branches will just get decay and potentially hurt the tree. The job does not look good, but hey the leaves are gone I guess? I have limited options to proceed, I cannot pay the $1200 for the repairs and Richards Tree Service says they won’t do anything on their side. 1. They should have trimmed the branches in smaller chunks. Not large ones that would drop on the fence. Make sure you have a video of their job if you go with them, and tell them to make smaller cuts. 2. They should use their insurance, if the insurance finds that my backyard is all moldy (which I do not see) then they won’t have to pay for it, this is why you have insurance. 3. They should improve their billing solution. Its 2020 and there are safer ways to pay online with proof of receipts."

"It went well. The job was performed to the specifications laid out in the contract. It was finished on time with a professional work crew. My one quibble with them was how they dealt with our plants. They were less attentive to making sure the property was restored to its previous state. However, they fixed the issue promptly once it was raised. I would recommend GeoFreeze for foundation and engineering work."

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."

Louis & Associates, LLC is a structural engineering consulting firm in Burke, VA since 2000. Luyi (Louis) Yan, the president and principal structural engineer, holds PE licenses in VA, MD, and DC with BS & MS degree in structural and civil engineering majors, and is the member of ASCE and NCEES. Mr. Yan had been a lead engineer in top national design firms, such as, Bechtel and PB. He has broad engineering knowledge and 25 years+ hands-on design experience in wood, masonry, steel, and concrete structures. He is familiar with current building codes, and local government's requirements for application of building permits. Louis & Associates, LLC and its long term associates would like to provide a full service of design including architecture, structural, and MEP (mechanical, electrical, and plumbing). Louis & Associates provides following services: -Structural analysis, design, AutoCAD drafting, and building inspection/evaluation -Including residential, commercial, industrial, restaurants, schools, governmental and religious buildings -Review, approve and seal structural drawings designed by others; -Building-code compliance analysis for building permit applications; -Building renovation/expansion design: add a new addition, pup-up, attic, dormer, stair, garage, deck and sunroom, finish basement and remove existing load-bearing walls and columns; -Structural damage investigation and repairing design, such as foundation settlement, retaining failure, basement wall/floor slab cracking, floor vibration/sagging, damages caused by falling trees, fire, snow, wind and reckless construction, etc. -Retaining wall and foundation underpinning design, -Light-gauge steel (LGS) framing and insulated concrete form (ICF) wall system design -Structural evaluation and repairing design for floor sagging, wall tilting and cracking, foundation settlement, structural damages caused by water, fire, snow, wind, seismic, overloading, and reckless construction.

"Louis was easy to schedule and was at the house within a week of me calling to schedule the inspection. Louis performed the inspection, relying on me to point out areas of concern and then taking some brief measurements and photos. However, he could not diagnose a main area of concern in second floor joists due to no access to joists either from above or below, and did not provide a solution or a diagnosis despite being paid for analysis. His visit was a turning point in the quality of service. His report was substandard. He did not properly document all needed repairs, and what he wrote in the report differed from what he mentioned in person regarding a failing floor joist. Multiple attempts were made to contact Louis by phone with voicemails and by e-mail to clarify discrepancies between the report and comments during his inspection, but he failed to communicate back to me. Overall, this service was not worth the $500 that it cost."

Structural Engineering questions, answered by experts

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

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.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits.
