About our external mastic in Great Linford
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we will confirm what access is needed. If you’re dealing with joints with sealant missing in places and weeds or debris growing in open joints, we can put it right.
Houses in smaller places like Great Linford 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.
All of our work is guaranteed for twelve months.

Looking after it afterwards
To keep the joints looking good and working properly:
- Never let anyone fill a movement joint with mortar
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Common problems we fix in Great Linford
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
- Old sealant gone brittle and cracked
Managing a site like Great Linford Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before you book
- Is VAT in the price?
- Whether all the old sealant comes out first
- How long to leave it before use
- Whether you can choose the colour
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the building, and the area is left clean. A visit to Great Linford is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

External mastic in Great Linford: local notes
Historic houses like Linford Manor (about 0.4 miles north-east) are a reminder that the area around Great Linford has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Andrew include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Wolverton station? Then split movement joints are easy to miss on a rental until damp shows inside.

Your questions about external mastic in Great Linford
I let a flat near Wolverton station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you do external mastic in Great Linford?
Yes, Great Linford is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us and let us know what needs doing and where.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We will give you a better idea when we quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
