New GAF Timberline shingles in ‘williamsburg slate’ color replaced the existing 2600 sq. ft. of shingles. To further protect their investment they chose a GAF Lifetime warranty.

Basement Finishing & Remodeling

If you are planning on finishing your basement, you can't go to just any regular contractor for the work. They will install wood floors, studs and drywall. The problem is that, while these will look great, they are organic materials. Organic means wood rot and mold when moisture is present. If you ever have a water leak, burst pipe or even heavy humidity say goodbye to your newly finished basement. We use completely inorganic materials such as:

  • Waterproof, Washable Insulated Walls
  • Mold-Resistant, No Sag Suspended Ceilings
  • Variable, Energy-Efficient Lighting
  • Carpet, Tile & Faux Wood Flooring
  • Accent Walls

Replacement Windows & Doors

We have dozens of maintenance-free options for windows and doors for your Ontario home. The materials include fiberglass, vinyl, wood, aluminum and come in different styles. Do you want a sliding door next to some aluminum set windows in the kitchen? Not a problem.

We are dedicated to the satisfaction of our customers. We want you to be satisfied with both the quality of our work and the job process. Because of this, we make sure our crews receive consistent training and install the highest quality products. Let's get started on your project today!

Job Stories From Ontario, NY
Ontario, NY - Increasing the R-Value Means Increasing the Comfort

Homeowners in Ontario N.Y. had 10 inches of blown-in Cellulose insulation put into the space above the garage to achieve an R-Value of 38. The R-Value of the insulation is important to this homeowner because he knows that the closer it is to the recommended value of 38 the more comfortable he will be in his home year-round.
