As a family owned Christian business since 1985 we have worked hard to build a solid reputation doing primarily roof repairs, tuck-pointing, skylights, flashing repair, basic roof maintience and inspections, gutter cleaning and gutter guards. I do the majority of work myself with my son and we never sub-contract. I have 40 years of experience and work is usually completed in one day. We take the time to show you exactly what we did by taking pictures of the entire process so that you know exactly what was done. Your satisfaction is our only concern.

"The work was substandard at best. I was deceived on the work that would be performed. I was told at the time of sales that the wood siding I had would be cut back and replaced with similar material. It was not. It was replaced with what appears to be a type of trim. I had originally called in because I wanted my house painted. They then only painted the siding and told me the trim would be extra after they had already started the job. At this point I felt like I was being held hostage to their demands. Since they had already started the job they would do what would normally cost over $2000 for around $1600. I elected not to have this additional work performed. I would have NEVER had them do any work had I known this from the beginning. There is caulk everywhere. Nothing was taped or masked. The paint lines are not straight or even. Sometimes they would paint the side of the trim the same color as the siding. In other places they wouldn't. They washed out their brushes with my house in my yard. One night they left the hose on. I asked them not to wash their brushes in my grass and one of them was rude about it. Do not recommend. The owner offered me $200 off for my troubles. I just wanted the job done right. This isn't it. A month later and I'm still waiting for them to come and touch up spots where they set their ladder against the wet paint and you can see marks on the siding because of it."

Insulation questions, answered by experts

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

While you should always insulate ceilings and exterior walls, you don’t always have to insulate the interior walls of your home to maintain energy efficiency. However, there are benefits to insulating every wall, including improved soundproofing and energy efficiency throughout your home.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.
