Window mastic in Pulborough
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We’re often asked to deal with cracked internal joints between frame and plaster and sealant in the wrong colour for the frame, on uPVC windows, patio & French doors and composite doors.
Around Pulborough, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
Big or small, it’s backed by our one-year guarantee.

How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
FAQs for Pulborough
Can you help a landlord with a rental near Pulborough station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is Pulborough within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you match the sealant to my frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we will use the nearest match.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
How long will my window job take?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Signs you need window mastic in Pulborough
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
It’s worth asking for a quote if you see:
- A bead that does not match the frame
- Untidy mastic left by window fitters
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
For landlords with property near Pulborough station, 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
- Is VAT in the price?
- Whether the sealant suits the joint
- What insurance they hold
- How hidden problems are handled
What we can’t put right
It helps to know what we cannot do:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
What we seal
- Aluminium frames
- Window sills
- Timber windows & doors
- uPVC windows
- Patio & French doors
- Composite doors
How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a morning for a couple of windows and a door in most cases. Parking around Pulborough is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
How to get a quote

Related advice
Windows and doors in Pulborough
With historic houses such as Old Place Manor (about 0.4 miles west) nearby, there’s older building stock in the area around Pulborough 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as The Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as St Mary's Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep drainage slots and sill grooves clear
- Avoid harsh chemicals near the mastic
- Keep paint off silicone joints
- Walk round the house once a year and look at the joints
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
How we quote for window mastic
The quote reflects the job in front of us. We take into account:

- Mould in or behind the old joints
