- Rigid filler in a joint that should flex
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
External mastic for homes and businesses in Rose Hill
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. Typical jobs include old sealant gone brittle and cracked and water getting into walls through failed joints, across façade panels, concrete & block and copings & trims.
Somewhere as small as Rose Hill, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Every job is covered by a one-year guarantee.

When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Rising or penetrating damp from elsewhere in the wall
- Movement that is more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
- Concrete & block
- Façade panels
- Joints between brick and frames
Different surfaces, different methods
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a small place like Rose Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

The process
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Rose Hill needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Getting ready for the visit
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises

Advice
Rose Hill buildings and the weather
With historic houses such as Cliveden (about 1 mile north-west) nearby, there’s older building stock in the area around Rose Hill as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Taplow station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as St Peter's Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What affects the cost of external mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- How many areas need sealing
- How easy the joints are to reach
- Any working-time requirements on site
Commercial jobs are quoted on the same basis as homes: 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.
What we need to know
To help us quote quickly, let us know:
- If someone has resealed it before
- How we’d reach the joints
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
How to look after the new joints
After the cure time, these simple habits help:
- Check external joints each spring
- Wash walls gently around the sealant
- Keep water from gutters off the wall
- Leave the joints unpainted unless we have said otherwise
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
