About our window mastic in Holywell
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you’re dealing with water coming in at the bottom corners of a door and gaps between the frame and the inside reveal, we can help.
Homes around Holywell range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Landlord and commercial work in Holywell
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep jet washers away from the mastic
- Paint up to the joint, not over it
- Check the mastic once a year
- Keep timber frames painted
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall.
When to call us in Holywell
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. That’s what backing rod is for.
Common reasons people contact us include:
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
For site and facilities teams at buildings such as St John's Meads Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- Who turns up on the day
- How hidden problems are handled
- Which colour the sealant will be
- When the joint can take water or movement
Window mastic in Holywell: local notes
Holywell is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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.
For landlords with property near Eastbourne station, renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as St John the Evangelist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works

For outside work, side access and the height of the joints help us plan.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
