FAQs for Holyport
Will you come out to Holyport?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Holyport in your area for window mastic?
Yes, Holyport is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Can you match the sealant to my frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
When is the sealant fully cured?
It depends on the product. Before we leave, we will tell you the cure time.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
How we handle window mastic in Holyport
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We’re often asked to deal with damp patches on the reveal after heavy rain and white mastic on grey or black frames, across window sills, uPVC windows and timber windows & doors.
In a village or hamlet like Holyport, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same 12-month guarantee.

Quotes for window mastic in Holyport

- Working hours on commercial sites
- The size of the job

Holyport homes and the weather
With historic houses such as Dorney Court (about 2.2 miles east) nearby, there’s older building stock in the area around Holyport as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.

Should I try it myself first?
If you’re set on DIY, put the effort into 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.
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.
How to look after the new joints
After the cure time, these simple habits help:
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
- Avoid blasting the frames with a pressure washer
Silicone can’t normally be painted, so mention any painting plans before we start. There are paintable sealants for joints that need it.
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.
