Walls and rooflines in Bentley
Historic houses like Farnham Castle (about 3.8 miles north-east) are a reminder that the area around Bentley has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Bentley (Hampshire) station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic in Bentley, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. If you are dealing with sealant that has lost its bond to the brick or render and failed sealant between panels on a façade, we can put it right, on brickwork movement joints, copings & trims and concrete & block alike.
Older homes in small places like Bentley may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Different surfaces, different methods
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.

Common problems we fix in Bentley
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
Managing a site like Bentley Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes anything from a few hours to several days, depending on the building. Somewhere as small as Bentley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
Getting a quote

Aftercare tips
After the cure time, these simple habits help:
- Keep soil, plants and ivy away from the joints
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
- Get split or bare joints resealed while the damage is small
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Bentley: your questions answered
Do you cover smaller places like Bentley?
Yes, Bentley is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Bentley for external mastic?
Yes. We work across London and the South East, and Bentley is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
How long will you be here?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we will say how long yours will take.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
How do you reach high-level joints?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Landlords, agents and businesses in Bentley

What affects the quote in Bentley
We quote each job individually. These are the things that affect it:
- The size of the job
- The old material and how stubborn it is
- Any mould that needs treating
- Which sealant suits the joint
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before work begins.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Where the job is, and your postcode
- The problem you’ve noticed
- Roughly how big the job is
- How we’d reach the joints
There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or send us an email.
Leave it or put it right?
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. The correct repair is a flexible sealant with the right backing. Where a wall is exposed, as many are in small places like Bentley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
