About our external mastic in Woolstone
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you have joints where the bead has come unstuck and failed sealant between panels on a façade, we can help, on façade panels, brickwork movement joints and joints between brick and frames alike.
Houses in smaller places like Woolstone can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. That’s where gutter joints and wall joints tend to fail first.
Your job is guaranteed for a year, as with all our work.

Signs you need external mastic in Woolstone
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we’re asked about most:
- Panel joints letting water in
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left

The process
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours to a few days, depending on the length of joint and the access. For a job in Woolstone, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Outside joints around Woolstone
Milton Keynes, which Woolstone is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time. With historic houses such as Linford Manor (about 2.4 miles north-west) nearby, there’s older building stock in the area around Woolstone as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Shepherdswell Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Historic houses such as Linford Manor, about 2.4 miles north-west, show how far back building around Woolstone goes.

Can I do it myself?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Common questions in Woolstone
Do older homes in Woolstone need their sealant replacing?
Often, yes: cracked, shrunken or mouldy sealant has done its job. New sealant won’t stick to old, so the old bead has to come out completely first.
Can you help a landlord with a rental near Milton Keynes Central station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Where do you work from?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
What should I tell you?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.

What else we do in Woolstone
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Show decorators and builders where the movement joints are
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Keep high-pressure jets off the joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Structural movement, which needs a surveyor or engineer
- Damp that is not coming from the joint
- Adding movement joints to masonry that has none
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
