Installed a mini split in my bonus room, which was 25 feet off the ground from the outside unit and not simple for wiring and copper. Had no issues and made everything look neat. Got the unit installed quickly and saved me money on some helpful suggestions.

They were very respectful. I hired them for leveling my front porch and they did it well. But I had a few more small jobs I needed done. They was very accommodating to hanging a light fixture, and installing my microwave vent hood. They are coming back to install new doors. I'm very satisfied

He had to purchase and hang wire shelves in the laundry room and garage. I was not home and he did a great job talking with me on telephone. My housekeeper was there to let him in. Very professional and friendly. Easy to work with. Would definitely call him again

Doorbell Installation questions, answered by experts

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.

Periodic checks for moisture or pest issues ensure consistent performance.

DIY insulation installation is feasible, particularly for basic rolls or batts, if you have the right protective gear and knowledge. However, hiring a professional ensures even, full coverage for maximum efficiency.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
