Window mastic for homes and businesses in Aldingbourne
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Typical jobs include leaking joints at the ends of sills and white mastic on grey or black frames, across window sills, uPVC windows and patio & French doors.
Around Aldingbourne, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Every job is covered by our 12-month guarantee.

What else we do in Aldingbourne
Aldingbourne homes and the weather
With historic houses such as Goodwood House (about 3.2 miles north-west) nearby, there’s older building stock in the area around Aldingbourne as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For an older house near a landmark such as The Parish Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Aldingbourne Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Aldingbourne questions
Is Aldingbourne within the area you cover?
Yes, Aldingbourne is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Barnham station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
How do I get a quote for window mastic in Aldingbourne?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can new window sealant be painted?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Honest limits
Before booking, it’s worth knowing the limits:
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a few frames, or a day or more for a whole house. In a small place like Aldingbourne, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Clear the area around the work
- Tell us about any water getting in
- Keep children and pets away from the work area
Getting a quote
Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand, and we’ll take it from there.
Advice
Do you need window mastic in Aldingbourne?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That is what backing rod is for.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that is falling out in pieces
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
Rented homes near Barnham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What to look for in a quote
- How hidden problems are handled
- The length of the guarantee
- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Avoid harsh chemicals near the mastic
- Paint up to the joint, not over it
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
Most silicone sealants will not take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Surface by surface
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.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
