- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
Looking after it afterwards
After the cure time, these simple habits help:
- Find out about consent before window work on a listed home
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Leave the new mastic unpainted
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic in Parkhurst
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead and we’ll explain which is best for yours. If you’re dealing with mastic dropping out of the joint and gaps round a timber door in stone or brick, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Parkhurst is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Every job is covered by our one-year guarantee, wherever you are in the Isle of Wight.

Is sand mastic in Parkhurst guaranteed?

Can you do sand mastic in Parkhurst?

Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Do you do commercial work?

Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant, and we will explain why.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you need sand mastic in Parkhurst?
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
It’s worth asking for a quote if you see:
- Gaps between timber frames and stone or brick
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
Managing a site like Hunnyhill Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

What sand mastic looks like in Parkhurst
Rainfall in the South East is lower than in much of the UK, 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.
Historic houses such as Carisbrooke Castle, about 2.1 miles south, show how far back building around Parkhurst goes.

Why act early in Parkhurst
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. In a small place like Parkhurst, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. In a small place like Parkhurst, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
