"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"I have had Art come over and install a Solar Tube in our bathroom, which was awesome and not only do I recommend Art, I recommend Solar Tubes in general!!

We moved into a house recently that has 5 skylights in it, all of them were ancient and energy sieves.  I had Art price up replacing with new energy efficient skylights, with solar blinds to add extra insulation.   I'm so glad I did, as the old skylights were not only in bad shape, and energy inefficient, they had leaks, and were poorly installed.   He put down drop cloths wherever he was working, and you'd never know the guys were there after they left.  Can't ask for much more than that!!

My new Solar Tube, Velux skylights and solar blinds are awesome, and I know they were pricey, but wow...totally worth it."

Drywall Insulation questions, answered by experts

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

When doing a DIY paint job, it can be tricky to achieve the perfect, straight line between your wall and ceiling. There are several methods, including lining it with painter’s tape and using the “cut in” brush tactic. Some homeowners choose to apply a thin line of caulk to the wall-ceiling seam to create the appearance of a perfect line.

You should leave a gap between drywall sheets because they naturally expand and contract along with the building framing as temperature and humidity change. Most pro drywall installers leave a gap of about ⅛ inch between drywall sheets, allowing the sheets to expand, contract, and shift without cracking or becoming damaged. If you don’t leave enough gaps between slabs, the edges will press against each other when they expand, and the pressure can cause visible cracks.

Yes, taping inside corners is a critical step in the drywall installation process.  Properly taping inside corners is essential for achieving a professional look, and an installation that resists cracking and maintains its integrity over time. Taping the corners involves the application of a joint compound along the seam where two drywall pieces meet. This process provides reinforcement, conceals the seam, and prevents future gaps or cracks from developing.

There shouldn’t be any gaps between your walls and ceiling. These can be fixed with joint compound but that is only a fix, and it’s much better if your drywall fits correctly in the first place. Sometimes gaps can appear if your foundation shifts significantly but if this is the case, you have a much bigger problem than patching drywall.
