"My only regret is not hiring Adam Contracting sooner. From the beginning of the project, I was updated on the schedule and cost. All of the employees were professional, and skilled, and left my house clean after each task. If I had issues or noticed something that needed to be changed the owner addressed the concern immediately. I am very happy with the finished project!"

"Mason was fantastic about keeping us up to date and walking us through any issues that were discovered during the process. I also loved they the crew stayed to complete the job and didn't work just a few days then come back a few days later, like many other contractors I have worked with. Everything looks great and I would definitely hire again for other projects I have around my house."

"The overall job went well. The (reasonable) estimate was performed weeks in advance of work. The work required 2 days. Scheduling was agreed on, & Manny confirmed a few days before the job. Manny power washed himself, but had a co-assistant on the paint project. Communications, punctuality, and work progress was very good. The finished job met my expectations. I only wish extra paint could’ve been left for touchups; but Manny did provide me with purchase info having brand/color of sealant used. A 3 yr warranty was also provided with receipt so that’s awesome. I’ve even obtained another estimate for possible painting of my siding."

"We took our time making a decision after getting the design and quotes, but Peter Belman patiently and politely waited us out, without changing the price.  We were amazed at how quickly they were able to do the garage and are extremely pleased with the result!

"ACI Design went above and beyond!! We moved on short notice and needed the whole inside of our house painted as well as outside power-washed. They came in and did a fantastic job and finished up early which is unusual in the industry. A few years ago we used ACI to put in flooring for us and again, they did a fabulous job and very timely! The owner, John Ayoub is extremely accommodating and walks you thru the process so there are no surprises. His crew was great and on time every day. HIGHLY RECOMMEND!!!!"

"Up until contract signing this company was amazing. They sent out estimators on several different occasions when I changed the parameters of the project, they would answer calls immediately, or respond to emails promptly, but that all changed once I had signed on with them for the project.
Starting the second day of the project (which was estimated at two weeks to finish) there were problems, mainly that no one showed up. Thinking that Maxsell knew what they were doing I did not inquire why they had not shown up, or communicated any reason why they were not there. The third day was the same story, no workmen showed up and I received no call/email/text about why. On the fourth morning I tried calling, emailing and texting, but got no answer until the end of the day letting me know that the mason had called in sick (no masonry work was actually performed until several weeks later).
Around the fourth week I was contacted and informed that they had chosen a different product and that they were loading it on the truck at the moment, but they had never discussed using a different product, and after I looked it up I found out that the new product did not include any of the warranties that the original had. Needless to say I was upset, but with a written guarantee from the company I felt I could let this slide.
Over the course of the six week project (I was told that it would be two weeks at the most) I spoke with the contractors less than a handful of times, mostly because they would not answer calls, the voice mail boxes were full and messages could not be left, and when contacting their office they would only reply through text or email.
So if you can wait 4-5x the estimate they give you, and you don't mind never being able to contact them, these are the contractors for you.

"I originally hired Daniel to perform a first floor kitchen remodel which included opening up the first floor with a more open concept floor plan. And adding a kitchen island. The project went smoothly and I was so taken by the final look that I had him come back to update three bathrooms, as well as, a complete remodel the basement. The house now has a more contemporary/ modern appearance and I receive compliments often. His price points for the individual projects were fair. I found him to be not as pricey as some and a bit higher than others. The workmen were polite, cleaned up daily before leaving and very repectful of my wishes. If I had to list a con it would be that one or two of the projects were not completed on schedule. Each being off by about a week. Overall, I would hire him again and have referred him to several friends and family members."

FAQs for greenhouse or conservatorium service projects in Washington, DC

Begin by choosing a build method that fits your timeline—either a ready-to-assemble kit for speed or a custom design for flexibility. Outline your goals, confirm the budget, and hire professionals for any electrical or plumbing work that requires expertise. Next, create detailed plans, select features such as heating, irrigation, and drainage, and choose a sunny, well-drained site. Following these steps puts your greenhouse on solid, efficient footing.

A small kit can be assembled in a weekend; a mid-size or custom build may take several weeks. The timeline depends on site preparation, material lead times, and whether you’re adding extras like electricity or plumbing. Allow time for grading, foundation work, careful assembly, inspections, and potential weather delays to ensure a durable, efficient structure.

Choose a style that matches your space, climate, and budget. Kits offer quick assembly and predictable pricing, while custom builds allow you to tailor the size, materials, and features to your specific needs. Compare options such as hoop houses, A-frames, or geodesic domes, and factor in local snow loads, wind, and sun exposure. A pro can confirm code requirements and recommend the most cost-effective design.

To seamlessly integrate your greenhouse, plan for both function and curb appeal. Position the greenhouse to capture southern light, keep it close to water and power lines, and match the exterior finishes to those of nearby structures. Proper grading, walkways, and surrounding plantings help the new structure feel intentional, rather than tacked on. A hardscaping professional can align materials and elevations to ensure the greenhouse blends seamlessly with your landscape.
