Aluminium Door Seals & Rubber Strips

Draughts, dust and water coming in around a door usually point to perished seals. An aluminium door seal with rubber strip or new brush pile can restore a tight fit without replacing the door. AluminiumDoor.co.za lets you request a free quote from an independent supplier or fabricator in your area for brush seals, gaskets, bottom seals and weatherstrips. They quote you directly, with no obligation. The service suits DIYers, contractors and fabricators, and fitting can be arranged if you would rather have the seals replaced for you.

Types of aluminium door seal

Brush (wool pile) seals: slide into channels on sliding and stacking doors to block draughts and dust
Rubber gaskets: compress between the leaf and frame on hinged doors
Glazing rubbers: hold the glass in the frame and keep water out of the bead
Bottom seals: drop-down, brush or rubber blade seals for the gap at the floor
Weatherstrips: adhesive or push-in strips for small gaps

Aluminium door strip and gasket matching

An aluminium door strip must match the channel it slides into. Pile height, base width and fin type for brush seals, and profile shape for rubber gaskets, vary between system ranges. Cut a short piece from the old seal or photograph it against a ruler, and the supplier can match it from stock.

Sealing against wind-driven rain and dust

Highveld thunderstorms and coastal wind push water sideways into door frames. A good aluminium door bottom seal, intact sill drainage holes and fresh glazing rubbers keep it out. Raised sills help on exposed elevations. In dusty areas, finned brush seals stop grit reaching the rollers. Sealing gaps properly also helps meet SANS 10400-XA energy-efficiency goals by reducing air leakage.

What affects the cost

Seals are sold by the metre or by the roll, so cost depends on the type, total length, quality of rubber or pile and how many doors are involved. Replacing glazing rubbers may mean removing the glass, so fitting is often worth arranging.

Comparing aluminium door seals prices

Prices for aluminium door parts change with profile, brand, finish and quantity. When quotes arrive, check:

Fit: that the part matches your door's system and profile; a photo or a sample of the old part helps.
Finish and material: colour match, and stainless or marine-grade components for coastal sites.
Fitting and delivery: whether fitting, adjustment or delivery is included in the price.
Trade terms: bulk pricing for builders and fabricators, and account options.

What to include in your request

A sample or photo of the old seal against a ruler
Door type and total length of seal needed
Where the problem is: draughts, dust or water
Whether you want the seals supplied only or fitted too

Frequently asked questions

How do I know my door seals need replacing?

Look for flattened or missing brush pile, cracked or shrunken rubber, draughts, whistling in wind, dust on the floor inside the door or water on the sill after rain.

Can I fit new door seals myself?

Brush seals and weatherstrips are usually straightforward. Glazing rubbers and some gaskets need the panel or glass removed, so ask for fitting if you are unsure.

Will a bottom seal stop water coming under my door?

It helps, but water ingress often also involves blocked drainage holes or a low sill. A supplier or installer can check the whole threshold.

Do you supply door seals?

No. We pass your request to an independent supplier or fabricator in your area, who quotes you directly and supplies the seals, with fitting arranged if you want it.
