"Had them come out to inspect my roof on Wednesday, and they fit us in by Thursday. Jordan Synoground's crew showed up exactly on time, they prepped my yard/general work area with tarps, and were done replacing my roof by 2pm. Efficient, clean, and solid work.

"Extremely disappointed with this company. They do not stand by their guarantees. Did install shower in one day. Was not provided with the shower head I ordered. Calking and trim work was very sloppy. Went through the shower wall into my bedroom, did sparkle wall and left it. Shower doors have leaked and was finally told six months later that there is nothing they can do to correct the issue. Originally quoted $24,000.00 for the walk on shower, eventually agreed to $11,500.00. Completely dissatisfied with my shower. Once they get their payment, they are done."

"We used this builder on the advice of another contractor. We are so disappointed. The simplest thing - putting composite decking down - was a disaster because they used the wrong screws (photo attached)! Our warranty is void now, but there's more! I was unable to upload all of the photos, but there is so much wrong I can't list it all here. The railings were put up wrong. The deck - even after three corrections - is still not straight to the house and so the steps are "crooked" to the patio. Because the composite boards have been reused three times now, we have holes with no screws (photo attached). He used 2x8s on the frame, but 2x6 joists - and when we asked where the joist hangers were - he added 2x4 hangers. On the screen porch roof we had to ask for gutters and when they were installed they were too short on both sides - so he stuck a piece of bent flashing under the shingles to "redirect" the rest of the water (photos attached). The entire project has been a nightmare and it's not over yet. Please do not EVER use this guy. I have no clue how he got a license.... and the best part? He put the WRONG license number on the contract!"

Insulation questions, answered by experts

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

When you insulate ductwork, you help protect the air moving through the system from external conditions and keep it sealed within the ducts. This makes your HVAC system more efficient since it doesn’t have to work as hard to heat or cool your home. Insulation can help lower your energy bills and prevent problems like condensation and mold formation inside your ducts.

Ductwork insulation in the crawl space is a simple add-on if you are hiring someone to insulate the entire crawl space already. Separately, it is only a few hours of work. The investment is nothing compared to the return since uninsulated ducts can lose up to 30% of their heating and cooling efficiency.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

DIY is possible for basic rolls or batts, but professional installation ensures even coverage and efficiency.
