"Working with Sino-America General Contracting was excellent from start to finish. Our project was a complete redo of the basement - we had demo'd floors, walls, and ceiling ourselves, and hired Mason and his team to help install a custom bathroom under the stairs complete with custom shower pan, under floor heating, and tiled walls. We also had them build a small mechanical room, install insulation, redo flooring, redo drywalls, build a drywall frame around the HVAC, install new vents and ducts, and install recessed lighting. They also built a bannister for the stairs leading to the basement and installed a matching railing and bannister for the upstairs. Finally the installed new doors for the upstairs and downstairs, and moved the downstairs door to the right a few inches in order to accommodate our design. This necessitated external brickwork and they were able to match the 70 year old brick extremely well. From the initial meeting Mason was responsive and professional as we went back and forth on the design of the bathroom. The designer (whose name I sadly can't remember) did a fantastic job with clever use of space and a keen understanding of how the design will translate into real life. Experienced in AutoCAD - they provided clear and very accurate 2D renderings and beautiful 3D renderings of the finished design, including 3D renderings of the style of sinks, toilet, lights, and mirrors we wanted. The contract was well presented and explained with the scope of the project clearly identified. At no point was anything unclear. He worked with a punch list with holdback until the punch list completed. Communication of contractor's needs and schedules were well coordinated with mine so there were no surprise missed days. Worked weekends to help expedite project completion. Any issues or concerns that we had during construction were explained or addressed right away. There was an accidental error during installation of the under floor heating and Mason and his team addressed it which required removing tile, reinstalling the heating system, testing, and replacing tile. They built a good relationship of trust with excellent communication throughout The quality of the work is excellent and stands up to close scrutiny. Smooth, crisp, and even drywall and corners, including on strange angles and niches. Beautiful, uniform color application Beautiful tiling and corners. The attention to detail was also very good. As an example we turned the remaining space under the stairs into a kitty-litter area including custom trapezoidal door and externally vented bathroom fan. Despite it being in a low-traffic area, all the work in that miniature room was of the same quality - crisp corners, well-joined shoe-moulding, and nicely painted edges. I recommend Sino-American Construction without hesitation."

"Our driveway was big enough for 1 car and we wanted it expanded to fit 2 cars plus have a walkway installed connecting the driveway to the main walkway leading up to the house. Tillerman Gardens was recommended to me by a friend. Jesse and his crew were wonderful to work with from start to finish. Jesse was very responsive to my request for an estimate. He patiently listened to what we wanted, asked great questions to get clarity and made some really good suggestions on things we hadn't thought of (i.e. adding river rocks to the grassy part at the edge of the driveway to ease getting in and out by the 2nd car). All the members of his crew were very nice and kept the yard looking clean at the end of each day. Work was done in the timeframe given to us. We are so happy with the end result! Attached are before and after photos. Would definitely hire them again for future projects."

"If you need to replace your underground oil tank, then you're freaking out about the expense and possible catastrophic complications.   So do yourself a favor and call Willard.    This wonderful family company makes everything easy.    

Our very positive experience started with the initial visit by Josh.    Then company owner Billy Willard answered all our many questions.   Considering the options, we decided to purchase a Roth tank.    Not just more compact than other brands, it also has a 30-year warranty.   Willard is the only company in Virginia certified to install Roths.    

Our work was scheduled quickly.    Willard called Miss Utility and also our county -- we didn't have to do a thing.   The Roth tank fit neatly into our garage and Billy and his crew took great care with every detail of its complicated installation.    The removal of our underground tank went really well too, even though the tank turned out to be quite deep.    Frank and Josh worked very carefully to expose but not damage the old tank, and to transfer oil into the new tank.    Then the old tank was prepared so the residual oil could be pumped for recycling.    We hadn't even realized this step would take place, because Willard had made all the arrangements.   Next the tank was lifted and soil samples were taken.      Then, using a truckload of fill Willard supplied as well as the excavated soil, the enormous hole was filled, carefully graded and sown with grass seed.     

You can imagine how many heavy vehicles were in motion to accomplish all this, yet there was not the slightest damage to our fence, landscaping, driveway or house. 

Meanwhile, Tim was connecting the new Roth tank to our furnace, working with ingenuity around the maze of ducting. pipes and wires in our basement.   He wasn't satisfied until he was sure the connection was perfect.   

We thought the entire crew was awesome, and that opinion was validated when the county fire inspector approved everything they'd done.   The Willards and Josh Delaney were not just expert, they were really friendly and considerate.    It was a pleasure to have them around,  They turned what had been a huge nightmare into a perfectly executed solution.

"We have a finished basement and a crawl space in the storage area of our basement.  We have found after large rain storms recently water has been increasing in our crawl space. After one storm we found over 6 inches of water above the gravel in the crawl space and purchased a temporary pump to pump out the water, discarded the plastic vapor barrier with concern of mold growing on it and began to see seepage through the foundation wall to the basement. 
In order to find a solution we scheduled four appointments with Angie's list highly regarded basement waterproofing contractors.  We were surprised to find that each contractor provided different solutions ranging in cost from $13,814 to $1,950.  We were impressed with Mr. Norfolk's honesty and straight forward approach.  He noted that he could do some of the solutions provided by other contractors with piping systems to a sump pump but suggested to start with a more cost effective solution of just adding a sump pump to the crawl area and replacing the current basement sump pump that was 27 years old.  If additional solutions were needed in the future he could preform them but why spend the extra money at this time if not necessary. The work was performed on February 1st and took two workman 3.5 hours to complete.  The workman explained how the system worked and asked that we please follow up if we had any questions.  The only area I could see improvement was clean up as after they cleaned up I had to again sweep the work area and vacum the carpets covered by their drop cloths. There was also debris and concrete mix left on the driveway.

"Andrew (owner) of Classic Drainage promptly responded to my online request for an estimate for what I called a French drain but later came to know it as a channel drain. Andrew asked me to send him some pictures of the area I wanted serviced. I took out my phone and snapped a few pictures sending them to Andrew. He then sent me an estimate where he also stated he needed to send someone out to take measurements to give me a more precise cost estimate.  His field rep calle dme within an hour and ararnged a tiem which was very convienant for me - the next day (a Saturday) at 10 am.  Andrew;s field rep was even early, took the measurements, provide more literature on what would be done. Very professional and knowledgeable.  What answers he did not have, was told the information would be provided as soon as possible. It was.
On the day the work was to be done, Classic Drainage arrived on time and started immediately. Andrew even explained exactly what would be done, how it would be done and how long it would take.  I was so impressed with the Classic Drainage work team. No breaks, constantly working. Completed the work, under my curious eyes, cleaned the site and it looked great. Nothing was damaged, not even our plants when they installed my new drain pipes.
I would definitely use and recommend Classic Drainage again.

FAQs for excavation major grading or resloping projects in Washington, DC

You can excavate in winter, but frozen soil slows down the process and increases labor costs. Many grading companies offer discounted rates during their off-season, so ask for a winter quote and weigh the savings against a longer timeline. A brief conversation with a local professional will help determine whether cold-weather excavation is suitable for your site.

Foundation digs can be completed in as little as three days or take up to three weeks. Soil density, access, weather, and hidden obstacles all play a role, so every timeline is a bit different. Have your contractor walk the site and flag any potential issues early—clear expectations help keep both the schedule and budget on track.

You must always call 811 before excavating. Dial 811 a few days in advance so that utility crews can mark underground lines and ensure the area is safe for digging. Hitting a buried cable or gas pipe can be both dangerous and expensive, and many municipalities will not issue permits unless the site is flagged correctly.

To remove soil during an excavation project, your crew will load the spoil into dump trucks with a backhoe or excavator, haul it to a disposal site, and return for the next load. Efficient hauling keeps the work zone clear and the project moving. Depending on the site and volume of osil, multiple trucks may rotate to maintain a steady flow.
