Wide Variety of Services Offered

Demo King offers services that can meet a wide variety of customer needs:

  • Demolition and excavation
  • Concrete and masonry
  • Remodel and renovation
  • New construction 
  • Solar
  • Solar storage
  • Government construction work
  • Asbestos testingand removal
  • Site clearing
  • Supplier for office, medical, and industrial products

Experience and Licenses

Demo King’s owner, Alexander Matthews, makes sure his crew members are educated in construction beyond demolition. Being in construction for decades before starting Demo King, he recognizes the importance of skill in the demolition process. Knowledge of plumbing, electrical, blueprints, and construction materials are all important when Demo King’s crew comes in to cap off lines, remove hazardous waste, disconnect, and facilitate the removal of large structure appliances.

Demo King does large commercial projects and has taken on projects as large as hospital demolitions and projects as small as bathroom remodels. 

The company carries the proper licensing and is EPA certified to do demolition work and manage asbestos removal. EPA certification is given from the federal government to contractors who are properly trained to remediate and remove lead contamination in home structures. 

Excellent Reviews

Demo King has a solid online reputation with customers highlighting punctuality, excellent communication, and genuine enjoyment working with its crew. Independent reviews are by far the most accurate indicator of what you may expect if you choose to hire a company, and Demo King’s report card shows all A’s. 

The company's owner claims that one secret to success is always answering the phones. We always appreciate coming across a company where efficient and timely communication is a standard. 

Many reviewers are so impressed with Demo King, they become repeat customers. This is also a great indicator of a solid company. 

Works with Local Non-Profit Organizations

In the demolition industry, many companies choose to just take everything they can to the dump, even when lots of property needing to be discarded has the potential for a second life. Demo King is unique as it chooses to donate much of these left behind items to local shelters and community organizations.  

Demo King partners with a Baltimore-based nonprofit called Second Chance. Demo King takes salvageable items from the structures it's demolishing such as doors, windows, fixtures, lumber, and hardwood, and donates to the Second Chance store. This gives the owner of the building, Demo King’s client, a tax credit for the donated items. 

This attention to being ecologically conscious is applauded as its not always cost effective. We love to see a local company do what it can to pay it forward and bless others with what others do not need anymore. 

Photo Gallery of Past Project Sites

Demo King has an extensive history of a variety of projects digitally documented on its website. We love to see stages of demo work that result in amazing restorations and renovations. This is a great tool for prospective clients to see the stages of projects that may have similar components of a job they need done.

The Bottom Line

We give Demo King a resounding thumbs up recommendation. The company can handle any job size and often is called in at hard times for clients. Demo King has a crew with the knowledge, experience, and qualifications we look for.

Many potential customers will be impressed with the company's dedication to recycling and donating to local charities. We are mostly impressed that it always has its phone lines answered by crew members that can help immediately. Responsive customer service is a key to earning customers' trust and it has paid off for Demo King.

Unfortunately, you won’t be able to use this company unless you live in Washington, D.C.

Joseph Hall Columbus, OH

My experience with demoking & expectations both have met after having my solar panels install by them. It was a very tough decision for me to select the installer who should be experienced & must be sounding local in my area, just to be on the safe side & have someone call out if maintenance is required in future. I believe demo king guys deserved a good appreciation in this aspect for doing a good job. I hope they wont let me down in future if I need them for any maintenance of my system.

After doing a lot of research, we decided on Demo Solar King because of their excellent reputation and their installation proposal, which provided the best value in terms of quality, cost, and after-sale support. They did not underestimate the length of the project as a whole or the amount of time it would take to return our upfront costs, unlike some other sales representatives. They provided prompt responses to all inquiries and took care of all the paperwork, including obtaining HOA approval and connecting us with an SREC seller. The reputation they had was deserved. There isn't a single thing they could have done better, in my opinion. For price, quality, service, and reactivity, they are unbeatable.

When I installed my home's solar system several years ago, I worked with Demo King Solar. They were very knowledgeable about the proper system I needed to install. They also completed and submitted all the paperwork necessary for the electronic firm to recognize them as a "energy producing station." Additionally, they produced all the necessary paperwork for grant applications. The equipment was accurately and expertly installed. They oversaw the setup all the way until the inspection. Additionally, Demo King Solar provided advice, produced and submitted the required paperwork for each SREC. And now not only I can save from Solar but also, I can EARN as well.

I have talked to couple of people about solar. I received the best advice by these guys during the initial sizing phase, from where I decided to choose Demoking as my solar panel installer. My installation has completed last week & I am quite glad with the decision.

The install work was completed by their own crew. Demo King communication during this period was really good. The permitting took few weeks followed by installation of solar panels & final inspection, but I'm overall satisfied with the result.

These guys have done a great job installing 34 Solar panels on my rooftop. I was concerned about the roof so much & they gave me 15 years roof penetration warranty unlike any other installer. Also they are locals so its a great deal to have this project done by Demo king team.

I recently had a solar panel installation done by Demo King Solar and it was a great experience. The project manager, Tony, was very professional and knowledgeable. He was able to answer all my questions and concerns. The installation process was smooth and efficient. I am very happy with the results and would highly recommend Demo King Solar to anyone looking for a reliable and cost-effective solar panel installation service.

It was a pleasure working with everyone at Demo King Solar! Joel was responsible for scheduling everything for installation, scheduling the electrical inspection, and providing regular reports on the progress of everything. From beginning to end, the process was straightforward. We eagerly anticipate future utility bill savings of a significant magnitude!

Chris was the one who was assisting me. He informed me that he had reviewed my electric bill during our consultation. He claimed to have never before seen one with such a low cost per hour. He also warned me that he had to be truthful: switching to solar power for me would result in significant costs and no financial savings. His honesty meant a lot to me because he could have easily completed the appointment, sold me the panels, and kept quiet. That's not how they conduct business, he added. Chris's honesty would have determined for me which business I'd call if I were going solar.

Our electric bill went from $150 and much more in the summer months. The year we had the Solar installed from Demo King Solar, we got a tax deduction from the government that covered most of the cost for system, rest we have significant savings on utility bills as well.
