"I have worked with Mason and his excellent crew on several projects…a basement dig-out renovation, a kitchen renovation, brick repointing, four bathroom gut/renos, and a living room/dining room gut and renovation. Obviously, I value his thoughtful cogent input, his excellent crew of various superb artisans, and his "brace and suspenders” thoroughness, or I would not have come back to work with him so many times! He is instantly available and totally reliable. The results of the work speak for themselves… these rooms are perfect and perfectly put together. I would not consider working with any other company. His excellence has spoiled me:)"

"After finding Tillerman Gardens online and requesting an estimate for substantial hardscape/landscape work on our newly renovated house, we were pleasantly surprised to find out that Jesse, the owner, actually grew up in our neighborhood! On top of being a Takoma Park local, and an all around friendly, honest, business owner, we also came to learn that he does great work as well! His team completely transformed our hardscape areas, including installing a beautiful flagstone walkway and patio, a perfectly graded cement driveway, iron railings on our steps, and plants in a number of locations. On top of that, some of the work required some touch up and sealing and Jesse and his team have come out a couple of times later this spring to do that work unprompted. There's a little bit left, but I know they'll be around to finish it as they've taken care of us every step of the way. Even better, everything was done in budget. Look no further! These are your go to guys for all landscape/hardscape work in the area!"

"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.

"The job was finished quickly and the construction debris was cleaned up. The basement was cleaner than when he showed up. The next time we had a major rain I got some water in the basement again. Steve came back as soon as it was convenient for me. No problems since then. His guarantee was real, there was no charge for rhe come-back.
I will be calling to have Steve come back to expand the drainage system when I have other work done that exposes another section of the basement.

"Andrew and his crew have always done an outstanding job for us.  He looks at every project with an eye towards drainage and keeping water away from the house--which was important in our case.  Andrew also goes above and beyond and recommends options that are cost saving.  Most recently, Andrew created a landscaping project for us in a very wet spot of our townhouse patio.  We had a general idea of how we wanted it to look, and Andrew provided an exceptional option for cost savings in placing a circular stone slab down.  The quality of work is consistently outstanding.  We would recommend them for any project you have."

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.
