External mastic for homes and businesses in Sparsholt
On houses, flats and commercial buildings across Sparsholt, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you’re dealing with failed sealant between panels on a façade and joints with sealant missing in places, we can put it right.
Around Sparsholt, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job, large or small.

When it is not the sealant
It helps to know what we can’t do too:
- Structural movement, which needs a surveyor or engineer
- Cutting new joints into brickwork, which is building work rather than sealant work
- Loose or hollow render, which needs re-rendering

What else we do in Sparsholt
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Sparsholt, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- 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
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive

Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a small place like Sparsholt, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Sparsholt questions
Do you cover Sparsholt for external mastic?
Yes. We work across London and the South East, and Sparsholt is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Sparsholt?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
How long before the joint can be used?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Hampshire.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep movement joints as flexible joints, not mortar
- Don’t let climbing plants root in the sealant
- Leave the joints unpainted unless we’ve said otherwise
- Tell anyone working on the walls about the movement joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind.
