Outside joints around Sprig's Alley
With historic houses such as Adwell House (about 4.4 miles west) nearby, there’s older building stock in the area around Sprig's Alley as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Saunderton station, outside joints that have cracked can let damp into a rental, so check them between lets.

Questions from Sprig's Alley
Will you come out to Sprig's Alley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Sprig's Alley?
Yes. We work across London and the South East, and Sprig's Alley is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
How long does the job take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. Your quote will say how long we expect yours to take.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
What the job involves on each surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Sprig's Alley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Look over the joints every year, ideally after winter
- Make sure movement joints are not pointed over
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
