"I highly recommend DES! I arranged a consultation after a home inspection report indicated that there was moisture in our basement walls. I was worried that costly mitigation efforts would be required. A friend who had previously used DES for a basement water problem highly recommend them, telling us that they were an honest company that only does what is necessary to solve a problem. Happily, Mark Fine from DES inspected both our basement and our exterior grounds and reported that there was no indication of cracks in the foundation or water intrusion, and that no work needed to be done. It is so refreshing to have a company that doesn't try to sell expensive services when they are not necessary!"

"Mr. Gomez and his crew worked quickly and efficiently. The final price was just 5% above the initial estimate, even when it involved some additional tasks not included in the original work agreement. The only minor issue that it took two weeks after the bulk of the work was done for the crew to come again to finish the final work. Nevertheless, I would be happy to hire Go Contractors again."

"If I could give this company a 6 out of 5 stars I would! They did a fantastic job overhauling my mother's deck, back patio, fencing, and front portico. All of the work was absolutely essential for safety and structural reasons, and I'm so glad I chose OSSA to do the work. My mother has Alzheimer's, which presented additional issues, but the entire crew was incredibly kind, respectful, and understanding of the unique challenges they faced. They were responsive and kept me aware of everything regarding the job along the way. My mother is so pleased, and I have the peace of mind that all of her outdoor space is safe, beautiful, and accessible. I will be hiring OSSA to do some work in my own home, as I look to make necessary improvements in the future. I've told everyone I know how how wonderful they are. 6 out of 5 stars!"

Woodbridge Plumbing Inc has been in business since Tom and Anne Kreutzer started it in 1973 in the basement of a house on Occoquan Road with just one plumber, Tom. After three years Tom hired his first employee, David McCullen, who stayed with him until Tom and Anne sold the business in October, 2006. As the business grew, it moved first to a rented space at Canfield Industrial Park for nine years, and then to the current office and warehouse in Telegraph Road Business Park in January, 1987, across Telegraph Road from the back of Target.

"AV was extremely helpful, put in the time to get everything right. And when I had a further question after the repairs, he called me back promptly. The office staff also has been unfailingly helpful and responsive."

Subcontractors questions, answered by experts

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

Depending on your structure, you may not need planning permission. Major excavation, anything that changes the external appearance of your home, or any construction that will affect your neighbors will need planning permission. However, no planning permission is required if you’re just converting an existing space into a root cellar.

The timeline for building a game room depends on the project’s complexity. Converting an existing room may take one to three weeks, while building a new addition or highly customized space can take several months. Factors such as permitting, material lead times, and contractor availability also impact the project schedule.
