External mastic for homes and businesses in Durley Street
On houses, flats and commercial buildings across Durley Street, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Typical jobs include joints pointed up with cement by mistake and brick movement joints where the sealant has split, on copings & trims, concrete & block and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Durley Street is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a one-year guarantee.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Walk round the building once a year and look at the joints
- Do not let climbing plants root in the sealant
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

Why deal with it now?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. In a small place like Durley Street, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

How the visit works

Advice
Do you need external mastic in Durley Street?
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
The problems people usually mention when they call include:
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
Rented homes near Hedge End station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
