Free computer drafting with general knowlege of design. I have 30 years experience in building houses. I am familiar with local subcontractors. I can get any job done at a reasonable cost.

"The work was done properly and when some additional jobs were added, Mr Grant went out of his way to get subcontractor's in to fix the added jobs promptly. I was very happy with the results and would recommend Steven Grant Construction to anyone who needed a prompt quote and a properly done job. He took the extra steps to finish my job within the quote so I stayed on budget."

"Like some of the other people have stated.. they are pricey and they are also extremely busy. We worked with Andy as the sales rep and he was a great guy. We told him what we were willing to spend at most and he made sure we got everything we wanted for that price. I think people who are new to construction work might see these guys as a hassle but in all honesty.. the men they had working for us were some of the hardest working and fastest working men I’ve ever met. Everything was done in a week and a half.. and it is STUNNING! My only complaint is that we were supposed to get it started 8 weeks after signing and it didn’t start til about 12 weeks.. like I said though.. it’s a very busy time of the year. COVID-19 has everyone at home with their honey-do list and EVERYWHERE is booked. I would absolutely recommend Cronkhite.. always negotiate on price.. and make sure to check the work being done. Don’t watch them do something wrong and complain about it after.. If you have questions then ask them!"

Insulation questions, answered by experts

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.
