Why it’s worth doing now in Anna Valley
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Around Anna Valley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours for a few frames, or a day or more for a whole house, depending on the amount of work. For a village or hamlet like Anna Valley, 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.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- 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 parking rules near the property
- Mention if the joints have been sealed before
- Tell us about any water getting in

Common problems we fix in Anna Valley
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
These are the problems we’re asked about most:
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What to look for in a quote

How we quote for window mastic
We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- Whether the work is at height
- Any mould that needs treating

Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

- Roughly how big the job is

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
When it is not the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Rotten timber, which needs a joiner first
- A sash or casement that won’t close properly
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Window sills
- Timber windows & doors
- Aluminium frames
- Patio & French doors
- uPVC windows
- Composite doors
Different surfaces, different methods
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
