Building Assessments: air quality, mold, water, solarBuilding Assessments: air quality, mold, water, solar

We can assess your Indoor Air Quality, Mold, and Energy Loss issues.  Each assessment is specifically designed for your particular needs. We typically assess the crawl space, air ducts, living area and attics for air leaks, mold growth, insulation levels, ventilation and filtration, poor indoor air quality, moisture intrusion and condensation, energy loss from air ducts, attics and plumbing. We then provide you with pictorial reports and a detailed, itemized quote that is comprehensive and easy to understand.



Closed Crawl SpaceClosed Crawl Space

There are two building codes for crawl spaces:  the open vent design and closed crawl space design.  We can make both designs more energy efficient, and free of mold. We have lifetime warranties for no-mold and a performance guarantee of no-condensation.  We are also certified for radon mitigation.



Attic Air Sealing and InsulationAttic Air Sealing and Insulation

We specialize in clean, cool, energy efficient attics.  We achieve this by:

  • Air sealing all floor, plumbing, electrical and HVAC penetrations.
  • Adding additional insulation; fiberglass, polyester, cellulose, or expanding foam.
  • Cover with a perforated radiant barrier to reflect the attic’s heat.
  • When applicable, install our patent pending Attic Ladder “Flip Cover”.

Customer Reviews

What our satisfied customers are saying about us:

“Overall, it went well.  There was a two-month delay getting my appointment on the calendar, but it was over the busy Thanksgiving/Christmas/New Years holiday season.  When the company connected with me, however, things moved very quickly.  Within a week, the technician arrived to inspect the house: roof attic, side attics, windows, doors, ducts, vents -- all three floors of it. He was professional and pleasant, and he was pleased to have me accompany him throughout the job, giving me a running commentary and answering all my questions.  He took photographs of problem areas and verified his findings with an infrared camera.  Within 48 hours, the results of his inspection and his recommendations, complete with highlighted illustrations from the photos he made were emailed to me by the project manager in a neat little report.  An itemized quote was also sent, pricing each problem area, and I was free to pick and choose any or none of the offered remediations.  From the scheduler to the technician to the project manager, it was a very positive and worthwhile energy audit of the home.”

“We were worried about mold as we had some leakage from upstairs showers. During the initial inspection, it was determined that the leaks were temporary (we had resealed drain gaskets), and there was no issue from the showers. However, the crawl space did show lots of evidence of mold. The suggested remedy for our air quality issues was to seal the crawlspace and especially seal up the wall that bordered the living space wall of the house (split level ranch). The intake ducts for the HVAC were completely unsealed and were drawing in air from the crawlspace. There was mold present all over this area. The estimate for was a solid day of work.

The crew was there early. Some focused on cleaning the ducts while others worked on sealing the crawlspace.  Everything was done exactly as planned.”

“IES was the third group that we had out and they were head and shoulders above the others.  They completed a very detailed inspection and walk through and produced detailed reports and quotes.  It was very clear that they knew what they were talking about.  The remediation work went very smooth.  I was very impressed with all the work done by this group to clean up a pretty extensive mold problem.  This entire group is professional, knowledgeable, customer focused and did fantastic work.”

“My daughter was convinced I had mold in my house. This visit confirmed we did NOT have mold. But this information I received about what could be done with my duct work and crawl space to improve energy efficiency was very helpful, and I probably will use this company again to make recommended improvements.”

“This company did a fine job in increasing my R factor from 19 to 48. Sealed my vents to the living area, cleaned the duct work, sealed the AC unit in attic, streamlined the duct work in attic for greater efficiency and finally added a layer of composite material to shield the heat in and cold out in winter and vice versa in summer to decrease energy usage.  Thorough crew, on time.”
