Fireplace Doors at Lowes – Hot Tips and A Review of their Selection, Pricing, and Support

Lowes fireplace doors

The goal of this review is to give you the information to get the best door at the best price from Lowes. The keys to getting the best door are:

1. Determine the type of fireplace in your home.
2. Measure your fireplace and see whether you need a small, medium, or large door.
3. Set up the Lowes page for easy shopping.

Here is a chart rating our experience with buying a fireplace door from Lowes:

Step 1: Determine what kind of fireplace you have.

Note: Lowes only carries doors for Masonry Fireplaces (brick / stone firebox and chimney).

Important: Lowes DOES NOT carry doors for Prefabricated, Zero Clearance, Factory Built Fireplaces (metal firebox and chimney) So if you have a factory built fireplace (EG: Heatilator, Superior, Majestic, etc.) you will need to find another source for your doors.

Example of a Masonry FireplaceBrick Firebox and Chimney – Found in older homes and made by masons. Lowes Doors work on this type of fireplace.

Example of a Factory Built FireplaceMetal firebox with refractory panels. Examples are: Heatilator, Lennox, Majestic, FMI. Lowes Doors DO NOT work on this type of fireplace.

No Factory Built Fireplace Doors???

Why doesn’t Lowes (and other Big Box Stores) sell doors for factory fireplaces? Because these doors must be fitted correctly and meet certain codes and standards. This means that for the majority of factory fireplaces the doors must be custom made. Typically these types of fireplaces and doors require a higher level of support that a mass merchant can offer. This is an easy DIY project once you get the correct door.

Step 2 : Determine the opening size of your fireplace.

As an example let’s find a basic fireplace door from Lowes for the fireplace below. It’s opening measurements are: 40¾” x 25½”.

I found the information on the Lowes site regarding how to measure your fireplace, so here is a link from Lowes that explains it nicely.

We need to find the right size door for our fireplace. Unfortunately Lowes makes this difficult. They only list part of the specs on their website – the largest size fireplace a door will fit. This can cause a problem as we will see later. A fireplace size that is too small and your door will not fit right. This is the big issue with all fireplace doors – a 1/8” can be the difference between a door fitting or being returned. Remember metal, brick, and glass doesn’t stretch or shrink.

To save you some time, here is the sizing chart on the Pleasant Hearth Website – it applies to all doors Lowes sells:

Based on the GHP chart it looks like I need a large sized door for my 40 ¾ x 25 ½ fireplace. It will be cutting it close. As you can see the GHP website makes it very plain that your fireplace must fall within the range of sizes listed, whereas Lowes just gives you the maximum size fireplace the door will fit.

Lowes fireplace doors sizing chart

It is VERY important that your fireplace is in the range of sizes listed on the chart above. Below are some examples of what can happen if you don’t follow the sizing chart.

The first example is of a fireplace that is 23 ½ “ high without the riser bar or a 25 ½” fireplace with the riser bar. Notice how you can see brick at the top of the opening.

Another reason that proper fit is important is that the bar on the back of the door that holds the mesh doors sticks out about an inch. It must fit in the opening of your fireplace or the frame of your door will stick out almost 1 inch.

Step 3: Set up the Lowes page for easy shopping 

Most people will head to the search bar and key in fireplace doors. The following page comes up:

This gives us every door Lowes sells (all 72). This is not easy to shop. I prefer good, better, best, sorted low to high.

Pricing of Fireplace Doors at Lowes 

Since a low price is the primary reason to buy fireplace door from Lowes, let’s see what they have to offer for some entry level price points for your fireplace.

Tip: Lowes only provides one picture and once the picture is opened it seems to be a low res picture that makes it very hard to see any detail of the door. Here is a link to the DS Pleasant Hearth website with more detailed pics.

Small, Medium, and Large Sizing

OK, here is one of my pet peeves with the small, medium, and large fireplace door sizing, and that is the huge overlap that can occur. I prefer more fireplace and less door. Here is what I am talking about…

The actual opening dimensions of the Alpine are 36” x 24”. That means I have 7 ½” of frame on the sides (3 ¾ Each Side) and 9” of frame on the top (5”) and bottom (4”). That is ALOT of frame. This is the way mass merchants can use a few sizes to fit a lot of fireplaces. It’s not bad or deceiving, but it can take up a lot of your fireplace. Check out the picture below. The first image is the Alpine Door from Lowes on our 40 ¾ x 25 ½” fireplace and on then the following image is a door custom made as an inside fit door. Notice the red dashed lines – that is how much bigger the door from Lowes is compared to a custom made door.

As you can see, buying your fireplace doors from Lowes was OK, yet not an ideal shopping experience. If you have masonry fireplace doors, and you do not need a lot of support, and you are not picky about the exactness of your fit, Lowes could be a great and inexpensive solution. These are common problems with the big box retailers for most products these days. Don’t bother looking for factory built fireplace doors at Lowes as they only pre-made small, medium, and large doors and for masonry fireplaces only. If you have a factory built fireplace, or you want to make sure you get a door that properly fits your fireplace, try another store than Lowes. They offer very low prices, but the fireplace doors are for masonry only, are inexact in their sizing, and there is very little support to assure you not only get a door that fits your fireplace, but can maximize its potential as well.
