Window & door mastic in Hyde, Hampshire
Window and door frames in Hyde need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
Different surfaces, different methods
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
Window mastic in Hyde, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on window sills, timber windows & doors and aluminium frames, and people most often call us about gaps where the sill meets the wall and water coming in at the bottom corners of a door.
Somewhere as small as Hyde, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
You get a one-year guarantee, the same in Hyde as everywhere else we work.

What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Hyde, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Common problems we fix in Hyde
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 cannot stretch. Backing rod sets the right depth.
Most people get in touch after spotting one of these:
- Damp patches on the reveal after heavy rain
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- White mastic on grey or black frames
Homes close to Church of the Holy Ascension include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
What your quote should include
- Whether the sealant suits the joint
- What the quote includes, VAT included or not
- What happens if they find a problem under the old sealant
- How much experience the applicator has
What happens if it’s left?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Hyde can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

FAQs for Hyde
Is Hyde within the area you cover?
Yes. Hyde is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with window mastic in Hyde?
All our work, in Hyde and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Window mastic in Hyde: local notes
Historic houses like Breamore House (about 4.4 miles north) are a reminder that the area around Hyde has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Hyde Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
