As a public service announcement, we’re filling you in on the 4 exterior renovation mistakes to avoid at all costs—before it’s too late.

Mistake #1: Falling For Gimmicks

Luckily, laws against false advertising prevent purchasing exterior products that are far off from your expectations. However, this doesn’t mean that gimmicks don’t still exist in the world of exterior remodeling. Low prices are often advertised the base model of products. This means the bargain window you have your eye on might not save you the energy you expect.

Before you commit to any company, be sure that you have the exact details on the product you’re purchasing—and avoid any unwanted surprises.

Mistake #2: You Try to DIY

Unless you have extensive construction experience or you’re a retired window installer, you probably shouldn’t try to DIY your exterior overhaul. This applies to windows, doors, roofing, siding, and even gutters. It’s so easy to overlook a detail that can cause thousands of dollars in damage.

For example, incorrect window installation can result in leaks around the window frames. These leaks can ultimately turn into water damage, which can even promote the growth of mold and mildew. Not to mention, you may need to repaint or even replace drywall if the wall becomes too damaged.

Instead of taking the DIY route, choose to hire an experienced professional instead.

Mistake #3: You Don’t Research the Company

Did you hire your remodeling company blindly? If so, this might be bad news. There are a lot of average Joe contractors who readily publish their own Facebook page and think they’re in business. The reality is that you have to think about insurance, experience, and ask to see a portfolio. It’s also smart to research online reviews for further social proof.

Mistake #4: Choosing the Cheapest Quote

If you’re on a budget, it’s tempting to choose the cheapest company to get the job done. However, this can quickly backfire. The cheapest home remodeling company almost never equals the best job—nor do they typically offer the best products.

Unfortunately, some companies will give lowball quotes just to get your business. Then they might tack on more charges or cut corners during the process—leaving you with subpar results.
