Our Experts were able to help a local homeowner from San Antonio find solutions to an extremely hot attic. The traditional fiberglass insulation that was already existing just wasn't doing the job so the customer reached out to Per-Foam-Ance by Doctor Energy Saver for help. With the experience of our team new, high quality insulation was installed using air sealing techniques to stabilize the temperature allowing the homeowner more comfort and lower energy costs!

To accomplish this, our crew used methods that included: Cellulose Insulation; Spray Foam; Receased Lighting insulation, hatch insulation, duct insulation; insulation of the traditional attic assembly. After two days of hard work our homeowner was already noticing the results and very pleased with our work.

We were doing some work on this customer's home, and noticed that they had some rotting wood trim above their front door. This can happen when untreated wood is exposed to the elements and can lessen the appearance of your home. The mold can eventually spread to other parts of your home. We were able to get permission from the homeowner to help them with this problem - at no cost to them! These homeowners were very pleased with the service they received and the updated look to the entry to their house!

Can lights are a source of tremendous air leakage between your attic and living space in your home. This air leakage causes air to be replaced or pulled in from another area of your home making your energy systems work harder and your utility bills higher.

Many contractors, especially in older homes often rush this step and try to seal the can lights but most of the time it is done improperly. We needed to remove the previous attempt at air sealing in order to properly seal these can lights, creating a conditioned space in the attic. 

In this particular home, each can light had to have a custom housing enclosure.  This is a major step in creating a conditioned space in your attic. This will lower your energy consumption and also make your family more comfortable!

Job Stories From San Antonio, TX
Ducts in the Attic - Part 1

Our crew was faced with a difficult challenge when they arrived at this customer's home. The customer was interested in attic insulation and was very vocal that they were already set on another company because of pricing as soon as we stepped into the door. We convinced them to let us give them a quote and compare it to the other companies quote that they had scheduled later on in the day. Once they agreed our team went to work!

We inspected their attic and immediately found a multitude of issues that were causing high energy bills, unhealthy environments, and an uncomfortable home. One of the most concerning issues was that their ducts in the attic were not sealed properly and they were wasting energy and more importantly the dust getting sucked into their home from the attic could be affecting their health. Our crew could also tell that the homeowner was trying to do what they could about their attic when they found an attic cover installed by the homeowner. However without the expertise of a Building Science Professional you are unlikely to achieve your goals alone. 

After our inspection we sat down with the homeowner and explained how their home was working as a whole and how it was not very energy efficient and could be effecting their health. We explained that both insulation and air-sealing was necessary for their home. They were experiencing issues from the stack effect and we knew how to fix it. After we explained our process, products, employee expertise and company mission they began to see why working with Dr. Energy saver was more beneficial. 

After we prepared a quote that included specials and discounts from that weeks promotion it was a no brainer for our customer. The homeowner ending up canceling the appointment with the other company, and started the job right away! They were so happy with their services that they hugged us as we left. Dr. Energy Saver provides services at a reasonable cost because we want to help you!
