I paid almost $100, one of the most expensive options online, so I could get a quality item for the front door of my $750,000 house and what I received has scratches and blemishes all over. I don’t want this as the front door welcoming piece. I want this replaced with a piece that is not scratched and is packaged in a manner to protect the finish (not just wrapped at each end). Please advise. Brian 415.999.0971

This has other content in it, but the first 10 seconds are of the threshold extender

I needed something to extend out past the brickwork without laying a soldier coarse. This threshold extender worked great for the new sliding door we put in. I set it in a grout on top of the old brickwork and it provided exactly what I needed.

The aluminum extrusion in the main picture is not what you receive which is the style i needed. How it attaches to your threshold is what's in the picture with dimensions. Did not work for the Jeldwen doors I have. Very disappointed.

Worked out for me to extend the threshold on this door I built. However the drawing of the profile and the actual extension do not match exactly. I had to modify it to make it work with my threshold (m-d). Next time I’ll get both from Pease.

I found this company and product online. What a very pleasant surprise at the rapid arrival and perfect fit! Thank you for making my project a success.

The 1st order was received damaged. I notified Pease who prompted sent the replacement. As you can see from the picture the 3/4" extension perfectly fits the Pease threshold. I found Peace product quality and customer service to be exceptional and highly recommendable.

We could not find a 3-4 inch threshold extension ANYWHERE except from Canada (and we don't live close) and they won't ship to the US anymore so that you all made one for us was the best. Thanks.

the customizable options, is great, and the product is pro grade and fits most thresholds

These are a great solution when most doors don't come with extended thresholds and nobody else seems to sell these and delivery was super quick and check out was easy

We knew it was a risk to see if it fit on our Jeld Wen door, and unfortunately it didn’t work out. It does look like profile needed, but not sure which doors this does work on. Bummer because of the high shipping cost being this extension to almost half the cost of the door itself, we’ll have to figure out how to Jerry-rig the thing on there. No final solution yet!

I BOUGHT 3 INCH X 36 INCH AND I RECEIVED 2 INCH X 36 INCH IM VERY DESAPOINTED.

You need to keep the customer inform of the delivery process. It shows up without any prior notification. Alos, the packaging could be little bit better. The piece was loose in the box.

The extender attachment is really solid, fits tight and the finished product looks like a single piece threshold. It was exactly what I needed.
Bruce B. 5/5 Verified
Unfortunately this was not compatible with the jeld wen door that was installed. The profile picture was misleading.
Jessie M. 1/5 Verified
They look nice, but the attaching hook is too large and would not allow them to snap and lock in. We had to trim them and glue them to the threshold.

Nice product, used it before, unfortunately it won’t fit on a Provia door. I would try it again on a Lowe’s door though.

Will work well with the added wall thickness of my continuous exterior insulation and rain screen siding.

Went on the website, found a part, ordered this, and received it in a short amount of time. The part was exactly what I was looking for, and it fit perfectly.

Good quality but the pattern on extender did not match photo online and therefore did not match what we had.

I experienced an issue with my order and was able to speak with a Pease door manager. They heard my feedback, were incredibly respectful and responded swiftly to make it right. Excellent customer service! That alone will have me coming back. Thank you!

Worked perfectly to fill the gap between the threshold and storm door. Install was a little time consuming but with patience you get a perfect fit.
