A septic system is something that is easily forgotten until something goes horribly wrong. What should you avoid running down your kitchen sink? Is one type of toilet paper safer to use than another? How often does your septic tank really need to be cleaned? These were just some of the questions that I had about my septic tank after it had backed up and filled my yard with raw sewage. Since then, I have spent hours researching septic systems so that I would not have to go through that again. I have developed my website to make learning about septic systems a little easier for others like me.
If it's been years since you've looked in your attic, you might be surprised at what you see. The insulation may be wet, moldy, or damaged by rodents. There could be gaps that let in cold air. It's easy to forget about the attic since you rarely have reason to go up there, but if it isn't insulated well, it affects the rest of your house. Here are some suggestions for getting your attic back in shape.
Clean The Attic And Close Gaps
Working in your attic may not be easy if the attic space is small and you can't even stand up. If it's difficult for you to seal gaps and put in new insulation, the hire an insulation contractor to do the job. Before you install new insulation, the old insulation has to be cleaned out first if it is damaged or wet because it won't be able to insulate as well as it's supposed to. Also, any gaps that show light from the outside should be sealed. This not only keeps out cold air, it also keeps out bugs and rodents that may get inside and tear up your new insulation.
Choose The Right Type Of Insulation
You can choose from batt, blown in, and spray foam insulation for your attic. If the insulation in your attic has batt insulation now and it's still in good shape, adding another layer of batt insulation might be a reasonable choice. The contractor may refer to the building codes that newer homes must comply with as a guideline on choosing the depth and type of your new insulation. If your attic is small, installing batt insulation can be difficult. In that case, blown in insulation might be ideal since it can be blown to far corners of the attic. Also, since this insulation is loose, it falls into irregular areas and gaps so your attic has a good seal.
Spray foam is another good option for your contractor to consider. It goes on as a foam that expands and then gets hard. It also flows into odd shapes and fills gaps, so it is an effective type of insulation. Price might come into play when you make your decision too. Batt insulation is the least expensive, so if you have a tight budget, applying fiberglass batt insulation might be what you need. However, if you have the budget for it, then blown in or spray foam could be better choices. Your insulation contractor can explain your options and recommend the best insulation for your home taking into account the condition of your attic and current insulation so you get the best results and see an improvement in your power bills.
