Windows and doors in Racton
Racton is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Warblington Castle (about 3.9 miles south-west) nearby, there’s older building stock in the area around Racton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Southbourne station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Racton Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Bourne Community College? Then its window and door frames need their mastic kept sound, just like a home’s.

Window mastic for homes and businesses in Racton
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you are dealing with water coming in at the bottom corners of a door and draughts coming in around windows and doors, we can help, on window sills, composite doors and aluminium frames alike.
Mastic can only go onto a dry, clean joint, so window work in Racton is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
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.

Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Racton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

What else we do in Racton
What affects the cost of window mastic
There’s no set price list, because jobs vary so much. What we look at:
- The type of sealant required
- The amount of work
- How easy the joints are to reach
- The old material and how stubborn it is
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The type of property
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
Need a quote? Please phone 0345 464 0079 or send us an email with a few details. You will know what we plan to do, and what it will cost, before any work begins.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
- Keep drainage slots and sill grooves clear
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Landlord and commercial work in Racton
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
Racton questions
Will you come out to Racton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Racton affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is the work guaranteed?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What information do you need?
A short description and the location. We’ll ask anything else we need to know.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
How the job changes by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the new bead is laid against the frame and the wall and tooled smooth.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’re 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 fails, we can still redo it.
The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. For a village or hamlet like Racton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
