Window mastic for homes and businesses in Goodworth Clatford
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. We work on composite doors, patio & French doors and uPVC windows, and people most often call us about whistling draughts around closed windows and cracked or shrunken mastic around the frame.
Homes in small places like Goodworth Clatford often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Goodworth Clatford, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
How long does it take to reseal the windows on a house?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.
What does window mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Surface by surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Do not paint over the silicone
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Ventilate rooms so frames do not stay wet inside
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
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.

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured for the work.
DIY sealant or a professional job?
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. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Window mastic in Goodworth Clatford: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Clatford Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Peter include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Andover station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- A sash or casement that will not close properly
