"when we noticed that the insulation in our attic was wet, we called Home Comfort. They came, look at the insulation, confirming it was wet and we had mold in our attic. They removed the wet insulation, put in new insulation after the mold was abated. The also added more vent tiles in the attic and sprayed insulation around the sole plates in our basement."

"The team were very professional, owner came at end of day to check up on quality of job (I asked him to look at my attic insulation, he could have easily conned me into paying for more - he didnt, and told me I didnt really need it... he found another insulation issue but recommended I solve it DIY style!)... so he wasnt interested in the $$$$.... Once he found I was happy with work he left me an invoice, no pressure to pay on the spot. The work has done exactly what he promised and I can recommend using them."
