"John was great. We hired him to replace 3 doors on my ground level to help modernize my home appearance. The job wasn’t as simple as I thought but John reassured me he’d get the job done and that’s what he did. He was on time, clean workmanship and quick turnaround. Definitely will work with John Lang and his partner Joe on future home projects."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Hired him to do a railing and install some doors and closets. Beautiful, meticulous work. They actually put on blue booties over their shoes, so clean. Communicative and fairly priced compared to other estimates."

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

Small jobs welcome

"Knew what was needed to be done immediately. When i hire someone for a project i hate being talked down to or not having something that i may not know explained clearly. This was not the case at all with Mr. Handyman of Huntington. They were friendly and explained everything that had to be done very plainly. I really appreciated the straightforward, no BS approach. They finished quicker than expected and even came in under the estimate! Another plus, of course. Lol. If you are looking for someone to do a project around your house, i cannot recommend Mr. Handyman enough. As you can probably guess at this point, i was extremely pleased with the job they did putting up my shed and wouldnâ t hesitate to hire them again."

Treehouse Builders questions, answered by experts

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Yes, proper grounding rods and conductors are essential for an effective system.

In most cases, you can attach a greenhouse to any type of house. However, certain factors need to be considered, such as the structural integrity of the house, available space, and local building regulations. You should consult with a professional contractor or architect to assess the feasibility and ensure proper construction methods.

The quickest way you can protect plants and trees from frost is to cover them with garden blankets or frost cloths. Also, bringing potted plants or trees indoors is much simpler than trying to cover and protect them outdoors. Remember to anchor blankets with something such as sandbags, fabric pins, or rocks if the forecast calls for strong winds to keep them from blowing away and exposing your trees and plants.

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.
