"Had the very best experience with this company ! They replaced my old deck added steps and extended roof over it! Beautiful attention to detail, showed up every day, got the job done in exceptional time . Berta is an absolute pleasure to talk with, she is so knowledgeable and offered suggestions when asked. Eddie and the crew were immaculate with keeping things neat while getting the job done. We would highly recommend Star Dynasty Construction and will be using them for assorted other jobs around the house!!"

Customers say: Quality work

"John is amazing at designing, and woodworking. My powder room is awesome, and the den, which was enlarged, and raised panel installed on the bottom half and up the stairs is jaw dropping. He is professional, reliable, and such a pleasure to work with. When I described what I wanted, he immediately knew what I was talking about, and which molding would look the best to accomplish the look. My highest recommendations go to him, and his crew."

"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."

"Lang Company Construction has managed several projects at our recently purchased home. John and his crew reverted our previously converted garage back to a fully functional single car garage. This project was particularly difficult due to some structural damage that needed to be corrected. Everything turned out great. John also managed the installation of our complete roof replacement. His crew did an excellent job. They left our property clean and the roof looks fantastic. He recently installed a new exterior front door as well as the storm door. Both work perfectly. John has also recommended other trades people for plumbing and landscaping projects around our house and they have all performed well. I would recommend Lang Company Construction for about any project someone had in mind. John’s experience, his attention to details and his commitment to doing things the right way is exceptional. We will continue to use his resources for more projects we have planned at our home."

"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."

"If there was a 10 star rating, I'd give him 10 stars! He was prompt and very professional. He rebuilt my old deck in one day and it came out beautiful. I wasn't able to be home and he kept me updated with the work he was doing and sent me pictures. When I ran out of material, he drove 20 minutes to pick up what I needed. He finished in one day and left the area immaculate. Highly, highly recommend."

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

Sustainable materials and energy-efficient designs support greener construction options.

Don’t forget to factor in the climate where you live during the planning stage. If your area is prone to bitter cold and heavy snow, you might want to invest in stronger greenhouse materials like a concrete slab, steel frame, and glass walls or plan to take your greenhouse down for the winter.

The choice is really yours. Greenhouses available in kits can make the job go quicker. You can find greenhouse kits to match your style and size needs. If you enjoy designing and planning, you can build your own from materials of your choosing. Just be sure to do your research beforehand so everything ends up structurally sound.

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 only real drawback to green building is that it’s more expensive up front, with per-square-foot prices sitting 33% higher than what you’d pay to build a traditional home. The higher cost is due to more expensive building materials and more labor to ensure every aspect of the home is as efficient as possible. However, green buildings often save money in the long run, so this is just a temporary downside.
