Parkhurst Window Mastic
Problem with your window and door frames in Parkhurst? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Damp patches on the reveal after heavy rain
- Black, perished sealant on frames
- Whistling draughts around closed windows
How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it, where a rigid one would crack.
Window mastic for homes and businesses in Parkhurst
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on aluminium frames, window sills and timber windows & doors, and people most often call us about untidy mastic left by window fitters and leaking joints at the ends of sills.
Mastic can only go onto a dry, clean joint, so window work in Parkhurst is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work comes with a one-year guarantee, wherever you are in the Isle of Wight.

Do you need window mastic in Parkhurst?
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Signs it’s time to call us include:
- Mastic that is falling out in pieces
- Water coming in at the bottom corners of a door
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
Carisbrooke Castle, about 2.1 miles south, is one of the historic houses in the wider area around Parkhurst.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Ventilate rooms so frames do not stay wet inside
- Don’t paint over the silicone
- Check the mastic once a year
- Don’t use solvent cleaners on the joint
Try not to touch the new joint while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
What we can’t put right
We’ll always be straight with you, so here’s what new sealant will not do:
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
- Faulty window hardware
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- Any working-time requirements on site
- The type of sealant required
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or drop us an email.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
What we do, step by step
The work is kept neat and contained to the joints we’re treating. The job generally takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Parkhurst, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

Advice
Parkhurst questions
Is Parkhurst within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do window mastic in Parkhurst?
Yes. Our work covers London and the South East, and Parkhurst is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
How long does it take to reseal the windows on a house?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we are fully insured.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.

Windows and doors in Parkhurst
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Carisbrooke Castle (about 2.1 miles south) are a reminder that the area around Parkhurst has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Hunnyhill Primary School, the mastic around its windows and doors needs looking after like any other building’s.
