Rated 4.0 out of 5.0 by Got the Job Done This window well cover does get the job done. I no longer have to worry about kids or animals possibly falling down the window well. Installation was as to be expected. There are supports to put at the window side of the cover and in my case I had to drill into the foundation to set the concrete screws which was a great excuse to buy a new hammer drill. However, the concrete screws included were very cheap and I had to go to the local hardware store to purchase new ones because the old ones kept snapping off (only cost about $3). The one thing I will note about this product is the same as some others have said. I don't think i would ever test to put 200 lbs on this product. I am confident it will keep my toddler out of danger and keep rabbits and squirrels from falling down there, but that is about it. I will say that I did a lot of research and for the money it seemed like this is one of the better ones on the market. If you want one that is more sturdy you will either have to have a company come out and fabricate one or do a metal grate. All in all, I am pleased with the product. April 14, 2015
Rated 2.0 out of 5.0 by Cheap product quality, could have been much better. This is not an impressive product at all. After installing it I put a little weight on it and did not try standing on it because I'm pretty sure I'd go through it. It should be ok for my 2 year old, which is why I bought it. I have 5 window wells and bought just one to test the quality. I will not be using these covers on the other windows. Usually HD has good quality stuff, not in this case. They are just too flimsy for the money. July 20, 2011
Rated 4.0 out of 5.0 by Overall it is a great product. The polycarbonate seems durable. We trimmed it to fit our window well with a fine jigsaw blade as recommended marked it 3/4 inch bigger, cut, then smoothed the edges with a belt sander. It took a little time but my husband and I were pleased with the results. We installed all four in a day. April 29, 2014
Rated 5.0 out of 5.0 by fits perfect We had just moved into a new home with an egress window in the basement. It was very hard to find a cover in the hardware stores that would not only fit, but would provide some sort of stability in the event someone walked on the cover. We were also concerned about finding a cover that would lock from the inside to help prevent breakins, but provide quick easy access out in case of an emergency. I found this product surfing the internet and discovered that you could purchase it at Home Depot. I was dissapointed that our locations in the Indainapolis area did not carry this cover, but had a great experience with ordering. The shipping cost was only $10.00 and in the even it didn't work you could return it at any Home Depot with your receipt. The cover worked out perfectly, it was east to fit and trim and the bonus was that it did have a locking system from the inside. I would highly recommend this product. May 2, 2010
Rated 5.0 out of 5.0 by Easy install My only concerns with this purchase had to do with fit and secure attachment to my window well and both were dealt with efficiently. A hacksaw blade on my jig saw did the trick for conforming the shape of the cover to my window well and the brackets that secured the cover were easy to install. The appearance is very acceptable and because the material allows light in means the basement room retains plenty of natural lighting. Specs say the cover holds 250lbs. I am skeptical of that figure - skeptical enough to not put it to the test. But for critters and small children I am certain it will hold up. I also purchased the 3 rung ladder and the cover accomodates that easily. May 3, 2010
Rated 5.0 out of 5.0 by window well covers Appearance is good, installation on metal wells not a snap. There are 2 aluminum struts for strength, I think there should be 3. I agree with the other reviewer, I will not test it at 250 lbs, but it will hold dogs and children. The ladder is well built but I think is overpriced. July 10, 2010
Rated 4.0 out of 5.0 by Good cover The cover is very easy to install. From the basement it looks really nice but from outside the house it's nothing special. Very easy to open from inside if there was an emergency. September 21, 2011
Rated 5.0 out of 5.0 Easy Install I bought these and although they were a bit pricey they were still a lot less expensive than custom covers. The directions were clear and easy to follow. They look nice and are able to hold my weight. July 10, 2010
