About our external mastic in East Lockinge
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. We work on concrete & block, façade panels and copings & trims, and common reasons people get in touch are sealant pulling away from one side of the joint and moss and dirt in joints with no sealant left.
Older homes in small places like East Lockinge may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How it 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 we leave things clean and tidy. In a small place like East Lockinge, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

DIY versus a professional finish
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Around East Lockinge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Your questions about external mastic in East Lockinge
Is East Lockinge in your area for external mastic?
Yes, East Lockinge is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Will you come out to East Lockinge?
Yes, East Lockinge is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Can you reach joints on upper floors?
Each building is different. Send us pictures and a rough idea of the height.
How much does external mastic cost in East Lockinge?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We will confirm how long when we quote.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Common problems we fix in East Lockinge
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
The problems people generally mention when they call include:
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
For an older house near a landmark such as Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
- Which sealant they’ll use, and why
- The length of the guarantee
Surface by surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one before sealing.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
What affects the cost of external mastic
