Is it time for cleaning or replacing windows?

Dirty, cracked and outdated windows can be an eyesore and a drain on your budget.

Washing windows can be a huge chore, especially if your home is two or more stories, but a good solution is to hire a window-cleaning business to put the sparkle back on your panes.

If it’s time to replace your windows, however, you’ll want to take time to thoroughly research your options regarding materials, style, glazing and installation, all of which could have a big impact on your wallet as well as your energy bill. The National Fenestration Rating Council’s window label will help you compare how well a window blocks cold, heat and outside air, allows light in and blocks condensation.

Ease in cleaning should be a consideration as well. Tilt-in sashes, for example, make it easier to keep the outside of your windows as clean as the inside without having to take off screens.

Whether you’re looking for a window cleaner or a window installer, the Better Business Bureau of Greater Houston and South Texas has these tips:

• Ask for recommendations. Check with family and friends and check the BBB at BBBHouston.org for reliable companies in your community. BBB Business Reviews provide a snapshot of the company, its BBB rating and reviews from actual customers.

• Ask for and call references. Request contact information and then reach out to the business’ clients from recent jobs to learn first-hand of their experience with the company and whether or not they would hire them again.

• Ask for multiple quotes. You should always shop around and get at least three quotes. Make sure all bids consider the same set of criteria. Remember that the lowest bid may not necessarily be the best bid; if one bid is significantly lower than the others are, the contractor may be cutting corners or may not understand your work requirements.

• Review the contract. Always get estimates in writing and never let any work begin without a written and signed contract. Do not be pressured into signing an agreement before you are ready and make sure you read and understand everything before signing. Take time to read the written contract thoroughly and make sure all verbal agreements are included.

Contracts should include start and completion dates, payment schedule — typically one-third up front with total cost paid upon completion — and a list of specifications and materials. Ask questions if you do not understand any part of the contract. Never sign an incomplete or partially blank contract.

• Get a receipt. Request a receipt marked “Paid in Full” when the job is completed and your final payment made.

• Keep your contract. Hold onto your contract for future reference or if any questions arise after the work is complete.
