External mastic for homes and businesses in Crookham Village
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on render & cladding joints, concrete & block and joints between brick and frames, and the jobs we see most are rain getting behind render or cladding at a joint and gaps where render, brick and frames meet.
In a village or hamlet like Crookham Village, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee, whatever its size.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep high-pressure jets off the joints
- Act on the first splits you see
- Keep soil, plants and ivy away from the joints
- Keep movement joints as flexible joints, not mortar
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. In a small place like Crookham Village, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Walls and rooflines in Crookham Village
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Farnham Castle (about 4.5 miles south-east) are a reminder that the area around Crookham Village has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near All Saints' Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Fleet station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.

What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
How long will you be here?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we’ll tell you how long to expect.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Why act early in Crookham Village
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Crookham Village can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Common problems we fix in Crookham Village
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
People normally contact us when they notice one of these:
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
For site and facilities teams at buildings such as All Saints Church of England Aided Junior School, larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before you book
- Whether all the old sealant comes out first
- How the surfaces are prepared before sealing
- What insurance they hold
- How the colour is chosen
