"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"We had a horrendous situation with a basement floor installation that went wrong leaving our house full of fumes, and a week later we discovered our basement was contaminated by asbestos in the process.  When we called Bill and Contractors Unlimited, they were extremely responsive.  Although other companies gave us bids, Bill was able to work his schedule to fit us in weeks sooner than the others.  Although the cost was a bit more, that saved us money because we were displaced and could not even go into our house because of the fumes.  CU set up negative air machines to replace the air, they followed asbestos abatement laws, they cleaned every item that could be salvaged in our house.  They even saved more than we thought which really reduced our overall expense.  Bill and his team were extremely professional, friendly, helpful, and really went out of their way to ease our stress from this situation.  At the end of their process, Bill arranged for a air quality inspection which we happily passed - able to return home.  I would gladly recommend Contractors Unlimited for asbestos abatement.  I just wish we had called them before the floor guys  created such a disaster.  Thank you Bill!

"They were great. I did not use them because someone that lives near me was a roofer, which I didn't know at the time of purchase, and they beat this companies price. Otherwise, I would not have hesitated to use this company.

"Fantastic work!  Fast, easy and professional.  These guys know what they are doing.  We also used Accurate Insulation last year when we bought the house, and they provided whole-house insulation to add to the original 1965 builder insulation.  They were able to provide advice on what would be too much insulation and could cause poor indoor air quality.  Would use them again anytime.

"They do quality work, but are messy and very difficult to work with.  They re-insulated all my windows.  There is yellow spray foam everywhere.  The siding was done ok, there are some sloppy cuts. They did not properly install the gutter guards.  They simply slid them in under the shingles of my roof.  They could have blown away at any time. 
They came to my house and just started to do the work without giving me notice that they were coming.  I showed up one evening from work and my siding was ripped off.  They could have damaged my car that was parked in the driveway.  
They have shady pricing.  They will send you a flier that says you can get 30% off with the flier.  My experience was that tthe 30% discount will only get you within a 10% range of the same pricing level of the competition. I also received multiple quote updates, negotiation, from these guys.  In one of them they randomly dropped the labor cost by 50%.  Their pricing scheme is really shady. 
After the work was performed, I hired a different company to work on my house.  They accidentally did some damage to work Four seasons performed.  Four seasons does not work well with competitors.  They act very unprofessionally if you use a different contractor for work on your house.  If you dare use another company to do work on your house, and that other company accidentally does damage, these guys act like catty 13 year old drama queens.  They will give you another excessively high estimate to redo the work and tell you that your warranty is voided unless you hire them to re-do the work.  They will not give part numbers, they will not give paint codes, etc. to you or their competitor to fix what the competitor accidentally broke.  They will be unresponsive to emails.  They wont call you back.  They will not send you emails, even if they agree to do it over the phone. 
The sales team is trained to try and upsell you at the cost of customer service.  It took me a month and half a dozen phone calls to get a list of all the materials they installed on my house.  
In sum, really difficult to work with.  Expensive. Shady business practices.  I would not recommend them.

FAQs for insulation service projects in Welcome, MD

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
