- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
Window mastic for homes and businesses in Pittswood
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have leaking joints at the ends of sills and a bead that doesn’t match the frame, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Pittswood is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You get a 12-month guarantee, the same in Pittswood as everywhere else we work.

Frames and glazing around Pittswood
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. Historic houses like Old Soar Manor (about 2.6 miles north) are a reminder that the area around Pittswood has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Hadlow Rural Community School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Tonbridge 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. If you live in an older home near St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The process
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Pittswood, 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 start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

What else we do in Pittswood
Leave it or put it right?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we’ll tell you. Around Pittswood, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.

Pittswood: your questions answered
Do you cover Pittswood for window mastic?
Yes. Our work covers London and the South East, and Pittswood is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Do you cover smaller places like Pittswood?

Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- A frame that has rotted at the joint
- Faulty window hardware
- A failed sealed unit that has misted up
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- Composite doors
- Patio & French doors
- uPVC windows
- Window sills
- Timber windows & doors
- Aluminium frames
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Wipe condensation off the frames
- Do not aim a pressure washer at the joints
- Keep timber frames painted
- Use gentle cleaners on frames and sealant
Silicone can’t generally be painted, so mention any painting plans before we start. There are paintable sealants for joints that need it.
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.
