  1. Larry L.

    Best covers ever! They keep my grandson and his toys from falling into the window wells. Nothing like these covers are available in the big box stores.

  2. George M.

    I could not find anything that could stop me from getting melted snow in my basement or from heavy rains. This custom fitted window well was easy to order thanks to clear measuring instructions from you. Thank you, problem solved.

  3. Robert S.

    Immediately made a difference with the moisture under my home!

  4. Joseph B.

    Kathy and Molly were excellent to work with. Both were very knowledgeable and helpful. I highly recommend them. After pricing our other companies I found them to be the most cost effective for my custom covers. So glad I find them. Great existence from beginning to end. The product is very good quality.

  5. Jackie B.

    I am so pleased with that one window cover that I will be measuring the other three in order to place an order. It is so neat and clean and well made– I’m impressed!

    What a difference from those cheap plastic ones that break, split, chip and crack…. I purchased new ones at least three times!

    It just took me a “procrastination period” before I actually told myself (old lady, you get out there and do it!!!). It is beautiful.

    Thanks so much!

  6. Herman L.

    Totally professional experience. I am a new homeowner so my handyman skills are very limited. Bob and whole staff guided me in measuring (and re-measuring) and purchasing 3 sloped covers. Installation instructions were very clear and unbelievably simple. Very good quality product with strong steel stabilizer bar.

  7. Timothy O.

    Customer service personnel were very helpful in making sure everything was right with my window wells, and covers.

  8. Sylvia M.

    Very easy to order and excellent service.

  9. Cory H.

    We had a great experience with WWE! Easy to work with, the window covers were easy to assemble and they look great!

  10. Eddie H.

    Your product may be the best item I have ever ordered online. I have never been happier with a product. I only wish I had more wells

  11. Cal K.

    We had a very good experience dealing with the staff to find the best product and the proper fit for the unusual design of our window well. We are very pleased with the end product.

  12. Dave S.

    Very professional people to work with. The covers are a perfect fit and an attractive solution to the age-old problem of leaves and debris accumulating in the window wells.

  13. Paul C., Lincoln AR

    Good product. You get what you pay for. Very thorough & insistent with design criteria.

  14. Frank, Madison WI

    Perfect fit easy to install

  15. Lawrence, Nashville TN

    I am satisfied with the fit of the window well cover and I wanted a couple inches overhang, which is great, but had to improvise a little to fasten it to the cement because the hinges hang over a bit too and could not get screws in the cement. So I made a clamp to put screws through to hold the hinge in place. I am satisfied with the covers and are very nice looking and will do the job.

  16. Cathy, Indianapolis IN

    Had great help on everything. If needed would order again. Would highly recommend.
