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

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

Insulation prevents heat transfer, which keeps your home cool in summer and warm in winter. Regulating the temperature in your home is not only more comfortable for you, but will lower your heating and cooling bills—it’s a win-win. Make sure to determine the correct amount of insulation to ensure it is enough for your home and climate.

If you have a number of large icicles on your roof, you may have an issue with insulation. This is particularly true if you’re also dealing with ice dams. A roofing contractor can diagnose potential insultation issues and help you come up with a game plan to solve them.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.
