Insulating a Back Porch Build-over Crawlspace in Wilmington, DE

Insulating a Back Porch Build-over Crawlspace in Wilmington, DE Insulating a Back Porch Build-over Crawlspace in Wilmington, DE

This detached brownstone row home, likely built in the late 1800s had an addition built over a previously existing porch. The owner wanted us to make the rooms in this addition warmer in winter.

An Energy Audit conducted by Lawson Home Service found the problem was the way the space under the back porch addition had been enclosed and insulated.

A Dr. Energy Saver's CleanSpace™ Crawlspace Encapsulation System was installed, which included installing SilverGlo™ insulation on the walls, and a thick layer of spray foam on the rim band between the floor joists. With this simple and effective method the insulation hanging from the floor was no longer necessary. The access door was replaced with an air tight EverLastTM Crawl Space Door.

Now the addition room will be comfortable all year long, thanks to the work of Lawson Home Service's hard-working crew.

This three story townhouse, built in 2007, had 7" fiberglass batts on the attic floor. The R value was approximately R18. 

This old insulation was removed to provide a totally clean attic floor. This is done so the attic floor can be air sealed, a crucial step in preventing expensive loss of conditioned air into the attic. In addition, it was necessary to re-route the bathroom fans so they terminated properly on the roof, rather than in the attic.
Once all the prep work was thoroughly completed the crew blew in a 17" blanket of TruSoft™ Cellulose insulation, tripling the R-value for a cozy comfortable R60. Kudos crew! The homeowner was happy with the results.

Attic access and storage. Attic access and storage.

A lot of the attics we go in require you to walk across joists or unsecure planks of wood to access air handlers, duct work, and attic fans. To the inexperienced individual it can be a dangerous area to walk and climb across.  Other attics have entrances and areas that aren’t securely blocked off from insulation.  This can cause insulation and dust to spill into unconditioned areas of your finished home.  


At Lawson’s we install secure, durable dams and decking. (1) We insulate the deck to make sure we are not sacrificing insulation and (2) we create a safe and secure way to enter the attic and if necessary service your air handler or other equipment located in that area.  As an addition we can even expand the decking for extra storage.

Attic, Crawl Space, & Blow-in Insulation

Why insulate your home? How about comfort and savings? Did you know that the combination of cracks, leaks, and openings in your house can equate to you leaving a window wide open. Rather than lose the heat or ac you are paying for make sure to insulate your home which will conserve the heat and cool air in your home and save you money in the long term in your energy bills.

We are your Wilmington professionals for blow in insulation and more. With years of experience insulating attics, garages, and basements you can trust us to provide expert care to your home.

Air Duct Cleaning

The air that blows throughout your house runs through a series of air ducts that most people forget about until they become a problem. If not cleaned the ducts become dirty and clogged resulting in air vents blowing less air through them and the air that is blown into your home is full of dust and debris. This is particularly harmful if certain members of your family suffer from allergies or asthma.

Cleaning out these air ducts is a needed chore that probably hasn’t been done in your home in years. Dr. Energy Saver is your air duct cleaning expert in Wilmington so make sure to bring this up during your phone call to us.

Crawl Space Repair

Get Crawl spaces are often left forgotten resulting in years of decay and damage before anyone notices. Mold, rot, and structural problems can become serious issues if not dealt with quickly. If you notice buckling floors, musty odors, heightened allergies or asthma symptoms, or cracks in the drywall it may be your crawl space is in need of repair. But don’t dismay our Wilmington team will repair your crawl space, fixing any issues.

After the work is finished along with correcting any damage and proofing the crawl space for further damage you may end up with the side benefit o saving up to 20% in heating and cooling costs with the improvements to the crawl space. Call us now to get a free quote for the work!

Job Stories From Wilmington, DE
Energy Audit in Wilmington, DE reveals many opportunities for improvement

An energy audit of this Wilmington, DE home, built in 1954, reveals many things typical of homes built before 1970.  Typically in these homes we see a lack of insulation, both in the walls and in the attic.  Outdated and inefficient heating and air conditioning systems is also found quite often. But by far the greatest source of energy loss is one of which most homeowners are totally unaware - AIR LEAKS.  The "blower door" test indicated the combined air leaks in this home have the same effect as leaving a standard size window open 6-inches, YEAR-ROUND!  Using an infrared camera (see picture) the auditor found there was no insulation in the walls of this home.  YIKES! Imagine how much the cost of heating and cooling have been for this unfortunate homeowner. 


Dr. Energy Saver recommends removing the nasty old insulation, then starting with a fresh clean attic floor so the tedious work of air sealing can be done properly. After the air sealing work is completed 17 inches of fresh, new, fire resistant TruSoft™ cellulose insulation is blown onto the attic floor. This upgrades the R-value of the insulation from R16 all the way up to R60, a four-fold improvement. That will surely bring down the cost of heating and air conditioning.

Crawlspace System Maintenance in Wilmington, DE

A technician from Lawson Home Services recently conducted the recommended routine maintenance on the dehumidification system that was installed in the crawlspace of this Wilmington, DE home several years ago.

Our technician conducted tests on the Sedona SaniDry™ dehumidifier and condensate pump to ensure their proper functioning. The technician cleaned and replaced the filter, as well as inspected all drain hoses to ensure there were no clogs and that they remained properly connected. Additionally, he tested the humidity levels in the air and the moisture content of the wooden structures in the crawlspace, both of which were found to be within ideal ranges.

Everything appeared to be in good condition within the crawlspace of this home. We plan to return in a year for the next scheduled maintenance.

Fixing Leaky Duct Work in Wilmington, Delaware

When checking the duct work in homes, it is proven that all duct work leaks. Stopping these leaks typically will have a lasting impact on how well you can control your heating and cooling inside of your home. But how to stop duct leakage is an on-going issue with homeowners.

Here in Wilmington, Delaware homeowners were experiencing just those conditions. With gaps inside of the duct work, not only did this cause their HVAC system to turn on more than it should causing higher electric bills, the leaks in the duct work caused debris, air pollutants, and other air quality issues to be blown inside of the home. Also, the house leaked so bad that they could not heat or cool one side of the home! Imagine living in a home where one side is too uncomfortable to even spend time in. 

Dr. Energy Saver was called to help solve the problem the homeowners were experiencing. We recommended Aeroseal which is a process that seals cracks and holes in new and existing air duct systems. Seeing the added benefits of how aerosealing your duct work could benefit you in savings off your fuel and electric bills, the homeowners agreed to the work. 

We tested their duct work before sealing up the holes and leaks. The home had 722.5 CFM(Cubic Feet per Minute) of leakage. That is equivalent to a 136.5 square inch hole which is about 433.5 refrigerators full of air loss every hour! After aerosealing their duct work, we reduced the leakage down to 25.5 CFM of leakage which is equivalent to a 4.8 square inch hole. Overall, Dr. Energy sealed up 95.5% of the duct leakage improving the overall homes comfort and health!

Reduce Odors in Wilmington, Delaware

When homes encounter high humidity inside of their basement, it usually leads to odd or musty odors seeping through the floor into your living space making your home stay very uncomfortable. Homeowners in Wilmington, Delaware were suffering from that problem. 

With humidity levels inside of the basement higher than what was expected, condensation began to appear causing those odd odors. After calling out Dr. Energy Saver who diagnosed the issues they were having inside of the basement, the production got to work. 

The first matter at hand involved removing the previous damp and foul smelling insulation inside of the basement. We then installed our high performance energy efficient dehumidification system inside of the basement to control the relative humidity levels inside. This prevents condensation from happening and also prevents the potential of microbial growth. 

After the work was completed, the homeowners noticed the odor was no longer. Overrall, another happy and satisfied Dr. Energy Saver customer!

Wilmington Homeowner Saves Crawl Space with CleanSpace Encapsulation Matting

Insulation trouble is a very annoying and possibly costly problem.  When Wilmington homeowner John M. and his wife noticed that one of their rooms was cold in the winter and hot in the summer, they decided to start looking around for a contractor. The couple found themselves at a local home show where they saw a vendor for Dr. Energy Saver Delmarva. John filled out a form requesting a free estimate.


Shortly after filling out the form, the couple was contacted by Delmarva who wanted to send out a representative to the couple’s home.  The couple was soon met by Delmarva representative Michael Alicknavitch to inspect their home.  John explained that not only did the specific room need improvement, but there was also possible work in the crawl space and ducts.  After inspecting the home, Michael agreed that John was right and began to explain products that would fix the couples problems.  In the crawl space, Michael noticed a build up of outside moisture, and for this he recommended the CleanSpace encapsulation system coupled with a CleanSpace drainage matting.  The CleanSpace encapsulation system is installed along the floor and walls of a crawl space and is designed to prevent outside moisture from penetrating into the confines of the crawl space.  The drainage matting is designed to drain all moisture within the crawl space to a sump pump or other installed drainage system.  Throughout the rest of the house, Michael recommended that the ducts be sealed, and the specified room be insulated with closed cell spray foam insulation.  This type of insulation is an “all in one” insulation and is ideal for any home, even with the most extreme problems.


After going through what exactly was going to be installed and how it was going to be done, Michael called in Delmarva’s Production Team One to complete the process.  John finds that he and his wife are no longer having insulation problems anymore.  Their home feels better than ever and it’s all thanks to the professionals at Dr. Energy Saver Delmarva!

Wilmington, DE Homeowner Insulates Home with SuperKneeWall Insulation

Wilmington, DE homeowner Tom H. found himself in a predicament when he felt constant drafts coming through his home, especially during the winter months.  After trying to replace the windows, the siding, and parts of the roof to stop the drafts, Tom decided he wanted a professional to come in and find a way to make his home more comfortable. Tom immediately went online to search for contractors in his area, and he was soon redirected to Dr. Energy Saver Delmarva whom he contacted.


Soon after being contacted, Delmarva sent out insulation specialist Michael Alicknavitch to talk with Tom and evaluate his home.  After greeting one another, Tom began to explain the problem he was facing to Michael and he showed him specific areas in the home where he felt a draft coming through.  Michael analyzed the specific areas and then asked to inspect the crawl space.  In the crawl space, Michael found that the insulation installed had deteriorated due to excess moisture that had accumulated in the crawl space over time.  After taking a look at a few other sections of the home, Michael began to explain solutions to Tom’s problem.  Michael recommended that specified areas of the home be insulated with SuperKneeWall insulation and other areas of the main floors be insulated and air sealed to prevent future drafts.  For the crawl space, Michael knew that the excess moisture had to be eliminated, so he proposed the installation of a CleanSpace encapsulation system. This system is installed along the walls and floor of the crawl space and prevents moisture from penetrating its surface and getting into the confines of the crawl space.  Finally, Michael recommended installing new insulation in the crawl space and air sealing it as well.  


Michael called in Delmarva’s Production Team One to complete the installation process.  Drafts are no longer a problem in this Wilmington home, thanks to the professionals at Dr. Energy Saver Delmarva. Tom is now finally comfortable in his home and can enjoy it to its fullest potential with friends and family for years to come!

Improving Home Comfort with Crawl Space Encapsulation & More

Over the years, Tom H. has replaced windows, siding, and the roof of his home.  He has also done other renovation work, but still the house is uncomfortable and drafty during the cold winter months.   Finally it was time to find a permanent solution for this undesirable situation. 

Tom H. searched online and found Dr. Energy Saver Delmarva- his local energy contractor.  Michael Alicknavitch is an energy specialist who checked out Tom’s home and determined that adding SuperAttic, spray foam insulation to the basement/crawl space, the SuperKnee Wall insulation and air sealing treatment, and the CleanSpace crawl space encapsulation system with SilverGlo would definitely solve his home comfort problems.

SuperAttic and SilverGlo are similar because they are both rigid foam insulation panels that fully seal and insulate the space they are in.  Each one is perfect for their application because it is not messy and will sufficiently and effectively slow the flow of heat.  Now Tom H. and his family can enjoy a comfortable, warm, and cozy home throughout the winter and not worry about drafts and heat easily escaping.
