"Tim and his team were fantastic. We planned for a significant renovation including several structural elements, carpentry, electrical, and siding and Horsman Builders delivered. Tim was a reliable communicator and addressed our questions in a timely manner. We replaced an entire roof, added walls, doorways, re-did a deck and covered porch, replaced doors, replaced siding, and added new outlets- to name a few. We felt like we could really trust Tim and plan to work with him again in the future."

"We have hired Ben and his crew for multiple projects, from small repairs to a beautiful deck, as well as a complete kitchen gut and remodel. Ben's attention to detail is impeccable. He continuously kept us updated with progress and milestones as well as possible budget fluctuations due to requested changes. We were absolutely comfortable with having the crew in our home while we were gone. We have been absolutely thrilled with each of the projects completed by Griffin Ridge Builders."

"We hired Adam to convert our single-car garage into a bonus room (framing, drywall, electrical, flooring, moved a gas line, rerouted the hose spigot, and replaced the garage door with a slider). The quality is fantastic. I’d recommend him to anyone. What really stood out: Adam cared about the details. I had a rough vision, but when we hit decisions I hadn’t thought through, he’d flag it and, if I didn’t have a strong preference, steer me toward the right choice. He had a real vision for how it should look, not just doing the bare minimum or blindly following directions. The other thing was how clean he and any of his crew kept their workspace. This didn't actually matter since they were in a garage we weren't using, but every day it was immaculate, and all the material scraps were removed. Hire Adam because he delivers excellent workmanship, sweats the details, and helps you make smart decisions along the way. Plus, he runs a clean, organized job site."

"I highly recommend Boyd Builders. My sunroom and deck were coming away from the house. Shawn jacked up both replaced footings, posts and drain pipes. Budget was clear from the start. He is professional and exceptional in his work. I have already recommended him to friends."

"We cannot say enough good things about Nick. He replaced all of our exterior trim and it looks incredible. It was a huge project and Nick did not disappoint! Nick and Marshall are both so kind, hard working, detail oriented and a pleasure to work with. They gave us updates every day and were very transparent about their progress along the way. We cannot wait to have NP Carpentry back for a future project!"

"Excellent professionalism! Very skilled, but willing to do many different “handy tasks” like curtain rods and hanging pictures. He easily put together small furniture from Amazon, but also does cabinetry, drywall, etc. I highly recommend Blake cleancut services!!"

"I could not have been happier with the service. Miguel was friendly, very competent, accommodating and respectful. Amy was great for scheduling. Miguel was on time and put up a street mailbox to my wife's glee. We will definitely reuse this service for our future needs. My highest recommendation."

"Nick Keech at Granite Shield was awesome to work with. He got my steps and railings done to meet insurance requirements and the brush and tree clearing made a huge difference—my yard feels so much brighter. Fair pricing, great work, and super easy to deal with. Definitely exceeded my expectations. Highly recommend!"

Customers say: True professional

"We started out looking for an architect/designer, and met the owner of Tseranos Construction, Sterg, in the process. He referred us to a design architect, which we used, and we ended up then hiring Tseranos Construction as our general contractor. Sterg was really great to work with. He found ways to keep costs down while doing everything that we wanted to have done. In the end, the garage construction project took about 5 months, but we are thrilled with the results. Would hire Sterg again for future projects."

Treehouse Builders questions, answered by experts

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.

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

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.

Yes, with proper heating or cooling systems and energy-efficient glazing.

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.
