Aluminium sliding doors for homes and businesses in County Durham

Sliding doors use large panels running on rollers within a multi-track frame. A two-panel door has one fixed and one sliding panel, while three or four-track systems let several panels stack behind each other for a wider opening. Panels can also slide into a wall pocket on some systems.

Keep sliding doors running smoothly by vacuuming the bottom track and drainage slots regularly, wiping the tracks with a damp cloth and checking the brush seals. Avoid oil on the track itself, which attracts grit. Rollers can be adjusted when a panel starts to drag or the lock no longer lines up.

Because sliding panels are bigger and have fewer frames than bifold doors, they show fewer and slimmer sightlines when closed. Slimline aluminium systems can have very narrow interlocks between panels, which keeps the view across a garden as clear as possible. The trade-off is that one panel always remains in the opening.

Making an opening wider for new sliding doors is structural work that needs building control approval and a correctly sized lintel or steel. Replacing doors in the existing opening is simpler. Flats, listed buildings and conservation areas may also need planning or other consent for the change.

What applies in County Durham

Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

For shops and other non-domestic buildings in England, Approved Document M covers accessible entrances, and Approved Document K requires large areas of glass that people could walk into to carry manifestation (visible markings).

County Durham has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Salt and sand collect in sliding door tracks near the coast, wearing rollers and seals more quickly, so tracks need more frequent cleaning. Stainless running gear, a coating suited to marine exposure and a raised threshold help on exposed elevations facing the sea.

Rural patios are often uneven or sit below the floor, so threshold height, drainage and level tracks need careful planning. Exposed sites benefit from stiffer frames, robust weather seals and laminated glass, as homes may be some distance from neighbours.

Sliding Doors in County Durham: questions

Why is my sliding door so hard to open?

A sliding door usually becomes stiff because of grit in the track, worn or seized rollers, or a panel that has dropped out of adjustment. Cleaning the track often helps, and rollers can sometimes be adjusted or replaced. If the frame has distorted or the panels are very heavy, replacing the doors is often the more lasting fix.

What maintenance do sliding patio doors need?

Sliding patio doors need regular cleaning of the bottom track and drainage slots, a wipe of the frames with mild soapy water and occasional checks of the brush seals and locks. Avoid oiling the track, which attracts grit. If a panel starts to drag, roller adjustment is usually a short job for a glazier.

Are sliding doors better than bifold doors?

Neither is better for every home. Sliding doors suit people who want large panes, slim frames and an uninterrupted view when the doors are closed. Bifold doors suit people who want to open almost the full width in summer. Sliding doors also take no space inside or out when opened, which helps on small patios and balconies.

Can I get sliding doors with a very slim frame?

Yes. Slimline aluminium sliding doors are designed with narrow outer frames and interlocks, and some systems hide part of the frame in the floor, walls or ceiling. Very slim systems need precise, level openings and strong support above, so the survey checks the lintel, floor and walls before recommending one.
