The previous contractor that laid the linoleum left ripples in the floor. It wasn't installed correctly. Top Notch Construct came in and did just that in the repairs, a Top Notch job. The team was also very professional and worked with me in understanding what they were going to do.

Those guys just terrific! They installed a whole house generator. It was a very hard installation, because the generator was far away from the electrical source. They have also followed recurring maintenance.

Steve was awesome. Called him on short notice and he came out the next day. Install was scheduled for the next day and completed. I didn't get the installers name, but he was all business and surprisingly, he did the installation alone. Great job and we got to see the gutters in action...

Doorbell Installation questions, answered by experts

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

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.

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.

They recommend sustainable materials and water-saving fixtures, tailoring choices to balance sustainability and style.
