Spring has arrived at last! Well, it should be coming soon, LOL…..anyways

The winter season has been challenging for all of us, but the silver lining is the pent-up demand from customers eager to replace their windows this Spring. Now is the perfect time to boost your sales!

We haven't increased our prices in nearly two years and continue to be the most affordable supplier in the region, with the fastest turnaround times.
There are talks of a second-quarter price increase, so this could be a great opportunity to motivate your customers who are currently considering new windows.
Keep in mind, due to industry wide increases in glass and vinyl cost many manufacturers have had multiple price hikes.
Our prices have remained the same, making us still the best value around by far!

And don’t forget, spring T-shirts are now in stock! Stop by when you come to pick up your next order.

Let’s make this spring a successful season!

You may not have heard of us, but we have been selling windows in Delaware since 2008.
We sell double hung windows as low as $209 for example and have an average lead time of 2-3 weeks for custom sized windows.
Why waste your time with the big box stores and stock sizes that need extra time to make them work, when we can get you windows $40 - $80 cheaper in most cases?

Give us a call or email to quote your next project. You won’t be disappointed.
