Choosing garage doors

Q: What do I need to consider when choosing a new garage door?

There are a number of things to think about when choosing a new door:

  • Would you like one that is manual or electronically operated?
  • Do you use your garage as a workspace, then you may also want to consider a door that offers insulation during the colder months.
  • Does your garage provide access to your home or do you store anything of particular value in your garage? If so you may wish to choose one that offers additional security.
  • How big is your garage and the approach. Garages with limited space and small driveway will find roller doors a good choice for ease of access and neat storage. These also offer options for increased security and improved insulation.
  • Are aesthetics important to you? Garage doors now come in a wide range of colours, finishes and materials to match your home and existing features. Our timber garage doors add warmth to your home. Or you could choose from aluminium plain colour doors, textured wood grain, metallic and wood effect finishes. Some of our range also allows for a completely bespoke finish with a powder coated to any RAL or BS colour.

Q: My garage gets cold and draughty. Can I get insulated garage doors?

A: Yes, our roller garage doors are perfect for keeping out the cold and draughts and minimising heat loss.

Installing Garage Doors

Q: How do I measure up for a new garage door?

Getting the measurements right for a new or replacement garage door is a slightly more complex task than simply measuring the existing frame.

The type of garage door you choose (e.g. sectional, roller, up and over) will affect the criteria used to specify and order the final door. For example the clearance area is different for each, as is the space required for installing and housing the operating mechanisms.

A fixing sub frame of some sort (steel or timber) is required for each door and this also needs to be taken into consideration when measuring up. Particularly where an existing sub frame is being replaced.

Another important factor is whether your garage door is being fitted in-between a brickwork opening or behind (inside) the garage opening.

When measuring for a new garage door having the following information available will help us find you the right door for your property.

Existing brickwork - width and height of the brickwork opening without the frame and door.

Existing subframe - width and height of existing sub frame if you are leaving it in place.

Internal headroom - measure the height of the space from underneath the lintel to the ceiling. (i.e. the space from the top of the opening for the garage door to the ceiling).

Internal return widths - the widths of the faces showing either side (left and right) of the garage door space. It's also worth noting any obstructions (pillars, doors, pipework) that may affect positioning, performance and therefore choice of garage door.

Q: How long does it take to fit a new garage door?

A: Depending on the type of door you choose, it will take in the region of 2 to 5 hours.

Q: How much does it cost to fit new garage doors?

A: We offer a free fitting service to anyone purchasing their new garage door from us.

Q: Is there a standard garage door size?

A: When we are asked what a ‘standard’ size garage door is, we often revert back to more traditional ideas of what size a garage door should be. The sizes used are 7’ x 6.6’ and 7’ x 7’ for up and over garage doors, and nothing else. These traditional sizes have generally been avoided since the 1980’s because they tend to be too small for modern cars. There is still a demand for these sizes to replace garage doors on older builds, but they are not a good size door for new builds. Now you find most builds have at least a 7.6 wide and 7.0’ high area.

Q: Do timber garage doors require maintenance?

A: In short, yes. But not in a way that missing a coating of wood treatment will ruin your entire door and you’ll need to have it replaced in a year. More so that it will ensure that your wood remains healthy, and that it always has 100% protection from water damage. If you would like more information about how to ensure the long life of your timber garage door, then please feel free to contact us on 01865 373973.

Q: Can I fit an electric opener to my garage door?

A: In most cases, the answer is yes. There are however some cases where the opener will not work properly or safely. If you have a garage door that was manufactured in the last 3 years, then there is a high chance that your garage door allows an electric opening mechanism. If your garage is older than 3 years, then you may need to check with your manufacturer. For more information about electrical garage door openers, please visit out Garage Door Automation page.

Q: Does a garage door mechanism need any maintenance?

A: There are some moving parts in a garage door mechanism that will need periodic lubrication to ensure efficiency. All manufacturers that are DHF member companies always provide their customers with a user information guide that gives maintenance information as well as safety advice. If you are unsure about any issues with your garage door, then we offer maintenance and servicing tO ensure the efficiency of your door.

Q: My garage doesn’t have much space; what kind of door would suit me?

A: There are many different kinds of garage door that are designed for garages that do not have much space. There are some door types that are perfect for limited space garage, these include the Overlap Garage Door and the Roller Garage Door. If you have a space problem in your garage but you want a new door installed, please feel free to contact us at GM Garage doors on 01865 373973.

Q: I have an electric garage door but it isn’t working, can I open it by hand?

A: In the event that your electric garage door isn’t opening (for instance there is a power cut or the batteries in your remote are not working) you are still able to open your garage door. Because of the varying makes and models of the electric motors used as garage door openers, you should consult an expert before trying to do it yourself. Our experts are always on hand to help you with any problems you may face, please contact GM Garage Doors on 01865 373973.
