"The installers came on time and were totally professional, experienced and worked continuously until the job was done. The triple pane windows are fabulous because compared to our old two pane faulty windows, not only are they solid and beautiful with no wind blowing through, but also the nearby road noise is greatly reduced. We needed to use plastic film to insulate the old windows and when the wind blew the plastic would billow like sails! The new windows make our condo seem like a true home."

Customers say: Quick response

"Elvin is great. He fixed my wood double front doors and applied paint that I had picked out, as well as new handles/lock. He took his time, was very polite, and made sure everything was in order before in left. My front doors look amazing. Will be hiring him again for more work around the house. Also, his pricing was very reasonable and on point for the amount of repair and painting work he did."

"We hired Budget Dry to review our basement problems and hired them to do the waterproofing project, install new basement windows, install the Santa Fe dehumidifier, and recently they installed our back-up battery system. We highly recommend them -always courteous, get the jobs done quickly and neatly, and always respond when we need their advice/want to purchase new filters. A great company!"

Windows FAQs, answered by experts

Depending on size, material, and labor, two windows can cost between $600 and $1,600.

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

Whether or not new windows increase property taxes depends on where you live and by how much your upgrade increases your home’s value. Smaller projects likely won’t result in increased property taxes, but it’s always a good idea to err on the side of caution and check. Contact your local county appraisal department for the most accurate information about property taxes in your area. 

Wood windows are often worth the cost because they add more to curb appeal and your home value than more affordable options like vinyl and aluminum. Wood windows also offer better insulation than vinyl and aluminum windows, and they can last about twice as long. As such, they’re more expensive up front but offer greater value and a higher ROI.

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.
