Window & door mastic in Hangleton, Brighton and Hove
Window and door frames in Hangleton need attention? We remove the old material, prepare the joints and seal them properly.

- Leaking joints at the ends of sills
About our window mastic in Hangleton
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have gaps between the frame and the inside reveal and a bead that doesn’t match the frame, we can help, on patio & French doors, timber windows & doors and composite doors alike.
Houses in smaller places like Hangleton can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Aftercare tips
A little care helps the new joints last. We recommend:
- Don’t use solvent cleaners on the joint
- Ventilate rooms so frames don’t stay wet inside
- Make sure the drainage slots aren’t blocked
- Wash the frames with mild soapy water
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Surface by surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Windows and doors in Hangleton
Hangleton is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Portslade Manor (about 0.9 miles south-west) nearby, there’s older building stock in the area around Hangleton as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Hangleton Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near St Helen's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Portslade station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. For a job in Hangleton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- Move anything stored near the joints

Questions from Hangleton
Does the coastal weather in Hangleton affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Portslade station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you do upstairs windows?
Usually, yes. We plan safe access before the job.
Can you match the sealant to my frames?
Normally, yes. Mention the frame colour when you ask for a quote and we will match it as closely as we can.
What should I tell you?
A short description and the location. We will ask anything else we need to know.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we will tell you.
Why act early in Hangleton
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Hangleton, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What you get with us
- Quality sealants from Arbo and Everbuild

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What affects the quote in Hangleton
Your quote is based on your job. We look at:
- Whether the work is at height
- Whether there’s mould to deal with
- How much there is to do
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Helping us quote
To help us quote quickly, let us know:
- Photos by email, if that’s easy
- Any previous sealing or DIY work
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
