About our window mastic in Hyde End
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you’re dealing with sealant in the wrong colour for the frame and gaps between the frame and the inside reveal, we can help, whatever the surface.
Somewhere as small as Hyde End, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, it’s backed by our 12-month guarantee in Hyde End and across Buckinghamshire.

Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as that is a job for a joiner.
For landlords and businesses
Landlords and letting agents in Hyde End can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Why it’s worth doing now in Hyde End
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Hyde End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Do you need window mastic in Hyde End?
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Keep an eye out for any of the following:
- Old mastic that has gone black or come away
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
For site and facilities teams at buildings such as Hyde Heath Infant School, its window and door frames need their mastic kept sound, just like a home’s.

How we quote for window mastic
Call for a quick quote. The main things that affect it are:
- How many areas need sealing
- The product the joint needs
- Working hours on commercial sites
- Access and height
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- If someone has resealed it before
- The address or postcode of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, call 0345 464 0079 or drop us an email.
How to look after the new joints
After the cure time, these simple habits help:
- Clear any debris from frame drain holes
- Keep solvents and bleach off the sealant
- Use gentle cleaners on frames and sealant
- Ventilate rooms so frames do not stay wet inside
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
