FAQs

Ball-bearing hinges are the most popular hinges for use on standard internal doors. These are fitted with hidden ball bearings within the knuckle of the hinge to offer smooth and reliable usage. These range from just £2.95 to just under £10.00 in price. For internal doors, we recommend using three 3" Ball-bearing hinges. 

Internal door manufacturers generally advise different trimming tolerances. To be on the safe side, we advise that you always check with any documentation provided, or contact us with queries on specific internal door types. Trimming over a manufacturer’s tolerance will void your warranty.

A primed internal door is one that has a primer, or undercoat, applied before painting. Primer assists in adhesion of paint to the surface, increasing its durability and offering additional protection.

Solid core doors can either be constructed from one piece of solid timber or made up of a range of materials including block and particleboard. They are dense, heavy and generally designed to withstand more force than hollow doors. They usually cost more than hollow core doors, but they are well worth the investment for the long lifespan they have. 

Due to their solid core construction, a solid internal door can offer improved noise reduction compared with a hollow door. There is a variety of simple and effective sound-proofing methods which can be used to improve sound reduction further, including padding.

Doordeals is also happy to source doors that come with a decibel rating for sound reduction, in addition to helpful noise reduction items such as acoustic drop seals. If you require any assistance, please do not hesitate to contact us.

The best wood for a solid internal door depends on a number of factors. For example, walnut doors are excellent at absorbing finishes and are highly versatile. Oak doors are beautiful and exceptionally durable. For more information about which wood is best for you, please contact us for advice and best practices, especially if high traffic or wet areas are involved.

A 30-minute fire door (also known as FD30) is a door that is designed to prevent the spread of fire for a minimum of 30 minutes. This is the most common type of fire door for residential use.

A 60-minute fire door (also known as FD60) is a generally thicker fire door that is designed to prevent the spread of fire for a minimum of 60 minutes. These fire doors are generally used in commercial or public buildings where there may be a greater fire risk and more time required to evacuate.

Building regulations state that internal fire doors are required between habitable rooms and stairwells in buildings over 2 storeys high. This does not apply to bathrooms or toilets.

A custom door is a bespoke model that lets you choose the height and width of your door if the size you require is not available as standard. If a style that you are interested in doesn’t offer this option, please contact us and we can let you know if it is a model one of our joinery shops could look to produce just for you. 

Bi-folding doors slide open while the panels fold into each other, stacking up against the wall or edge. This is called a concertina (or accordion) effect. The key benefit of this is there is less space required to open them. A regular door requires space in front of it that is equal to its width, so that it does not hit anything when opened. Bi-folds do not require this.

Bi-folding doors can be fitted to open both inwards and outwards. You can choose to have your doors open inwards or outwards depending on your own preferences. Outward opening bi-folding doors are more common because there are more likely to be obstructions (such as furniture) on the inside of a door than the outside.

Tracks are an integral part to how a bi-folding door works. The tracks are the mechanism which allows the bi-folding door to open the way it does. Your tracks should be kept clean and dust-free to keep the opening of your door smooth and effortless.

When choosing the correct size, it is important that you know if your door is listed including the frame, or if it is just the door size. This will have a big bearing on whether the door is suitable for you. If you have any queries relating to this, please get in touch.

Custom doors are available both pre-glazed and ready-to glaze. You can use the filters on the left hand size of this page to select this and view all doors that can be glazed or come pre-glazed.

Yes, door frames can be removed and replaced if they are damaged or warped, or if you simply want to update for aesthetic reasons. Replacing a door frame is not difficult, and you do not necessarily need past experience, but we recommend hiring a professional to replace for you if you are unsure of exactly how to do it. 

Yes, your internal door frames will generally be made from the same material or material that is similar to your doors, and they can be painted or finished in the same way. Just make sure you apply even amounts of stain or paint to ensure the results are consistent between door and sidelight.

Alternatively, paint can be used to create a contrast and feature of the door. A popular combination is a white frame around an Oak door, to create a feature of the Oak door.

The internal door frames we sell feature solid timber cores, which are strong, provide a good hold for screws and fixings, and look great too. The veneer laminated construction has the advantage of extra stability and material economy without losing authenticity.

If you need door frames that are fire-rated, Doordeals can help you. We offer frames which when used in conjunction with the right internal fire door and component parts, achieve an FD30 or FD60 fire rating. 

Heat can escape from a room through any unnecessary gap. This includes keyholes and the space between the door and its frame. Draught excluders help by sealing this gap and keeping the heat inside the room. They also help prevent cold air from getting into the room.

Draught excluders sold by Doordeals are made from a variety of materials, including long-life plastic, nylon/rubber, and metal (which includes four versatile colours). 

Our range of draught excluders includes nylon/rubber weather seals, which are available from just £8.00, as well as standard “around door” seals which start at £17.50.

Intumescent strips are ideal for fire rated timber door edges and frames, while nylon/rubber weather seals are suitable for any door frame. Standard “around door” seals are very durable and great for external doors susceptible to more severe weather conditions.

External doors are constructed to a different specification in order to help stand up to the elements and better serve the different purposes they are to perform. External doors are often heavier and thicker than the majority of internal doors. 

There is a variety of hinges that can be applied to external doors. A commonly used hinge on external doors is a butt door hinge. Other types of hinge that can be used on external doors are antique door hinges and hinge fronts (typically used on traditional properties, such as cottages), and parliament hinges, which are often used on patio doors.

Pre-hung doors for external use vary in size and dimensions. The external pre-hung doors we sell at Doordeals range from 762mm (30”) to 915mm (36”) in width, and from 1,981mm (78”) to 2,134mm (84”) in height. All doors sold in pre-hung sets come with a thickness of 44mm. 

To correctly measure for a pre-hung door, you must take note of the following:

• Jamb width: This is the backside of the interior trim to the backside of the exterior trim.
• Rough opening: This is the opening between each framing member, as well as from the bottom of the sill to the top of the opening.
• Exterior opening: Also known as the masonry opening if the door is surrounded by brick or stone. This is the measurement from the outsides of the exterior casing, and then from the bottom of the sill to the top of the trim. 

Yes, an external pre-hung door can be painted. Whether this is done before or after installation depends on the door type and the preferences of the person painting; however, all painting and treatment must be completed before the door is exposed to the elements. Some doors can be unwieldy when not attached to anything, making it easier to make mistakes and accidentally damage the door.

External glazed doors are constructed with glass panels, which act as windows through the door. Glazing is designed to allow more natural light into a room and to help create an elegant look for the exterior of your property. 

Yes, stable doors are a secure external door solution that works perfectly for front and back main entrances. The security qualities of your stable door depend on a number of factors, including the material it is made from and the kind of locks you have installed. It is obviously important that to keep a stable door secure, a good lock is fitted to both upper and lower sections.

Old fashioned stable doors were known to be quite draughty – this is not the case for the stable doors we sell at Doordeals. Our doors are constructed from sturdy, high-quality wood and offer superior draught resistance compared to traditional models.

Hardwood stable doors can be fitted to open both inwards and outwards.

Stable doors can be locked in a number of ways. The most commonly used method is to install a 5 lever mortice sash lock on the upper section, which includes a latch and deadbolt. It is recommended that the deadbolt be locked with a key, while the latch bolt can be operated manually. For the lower section, a key-operated 5 level mortice deadlock can be installed. You should ensure your locks all adhere to British Standards BS 3621.

When installing your new external ready-to-glaze door, we always recommended installing your door so that the loose beading is on the outside. This helps to stop water ingress and creates a step for the water to run down under the loose beading. Always use glazing silicone sealant or glazing tape to ensure your glass is secure and that gaps are sealed to prevent draughts or leaks. 

Our single toughed glazing is 4mm thick. 

When choosing single glazing, please be aware that this may create a "step" on the door where the beading is fitted. 

Our clear double-glazing options are 14mm thick. This is made up of 4mm glass, 6mm gap, and 4mm glass (4/6/4). 

The heritage glazing options are 16mm thick. This is made up of 4mm glass, 8mm gap, and 4mm glass (4/8/4). 

The energy efficiency of our glazing varies on the type of glazing you choose.

Clear Toughened Double Glazing

Our standard double-glazed units are air-filled; with a U-Value of 3.3.

The lower the U-Value, the better the energy efficiency. 

Clear Heritage Glazing

Our heritage units are argon-filled; with a U-Value of 1.7. This is are our most efficient glazing. 

The lower the U-Value, the better the energy efficiency. 

Please note, unless otherwise stated, our doors are not Part-L rated. 

Yes! Unless otherwise stated, our glass is toughened as standard. This means that it will meet current safety standards.

By law, glazing must display a safety mark or "Kitemark" to prove it conforms to the correct standards. This will be visible on all toughened glazing panels that we supply and cannot be removed. 

Please note: Float glass cannot be supplied toughened due to the small area size.

On all our external and internal doors where there is a choice of glass option, we do not always fit the glass into the door. The glazing may be sent separately from the door or the door will arrive with the glass temporary pinned in place. Should you require the doors to be properly glazed please mention this at the time of order or contact us prior to placing the order. There may be a charge for this service depending on the amount of glazing required.
