Window mastic for homes and businesses in Up Nately
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just call 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached for window mastic in Up Nately. If you are dealing with water coming in at the bottom corners of a door and mastic that has split away from the wall, we can put it right, on timber windows & doors, composite doors and patio & French doors alike.
In a village or hamlet like Up Nately, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
So the new joints stay in good condition:
- Walk round the house once a year and look at the joints
- Ventilate rooms so frames don’t stay wet inside
- Do not use solvent cleaners on the joint
- Do not aim a pressure washer at the joints
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house, and the area is left clean. Somewhere like Up Nately needs a little journey planning: 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 look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Mention any tricky access

How we quote for window mastic
Your quote is based on your job. We take into account:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The product the joint needs
- Access and height
Doing several joints on one visit is normally more efficient than separate visits. We will give you a clear price for the lot.
Helping us quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- If someone has resealed it before
- The address or postcode of the job
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Why it’s worth doing now in Up Nately
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Up Nately, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Signs you need window mastic in Up Nately
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch when they notice something like this:
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
- Sealant in the wrong colour for the frame
If you live in an older home near Church of St. Stephen, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- What insurance they hold
- Who turns up on the day
- How long to leave it before use
- Is the old sealant removed completely?
What we can’t put right
Sealant is not the answer to every problem, and we will tell you before we start. It will not solve:
- Condensation trapped between the panes
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Timber windows & doors
- Aluminium frames
- Window sills

Frames and glazing around Up Nately
The South East is one of the drier parts 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 Hook station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Robert May's School, its window and door frames need their mastic kept sound, just like a home’s.
