Questions from Amport
Do you cover smaller places like Amport?
Yes, Amport is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Grateley station?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Can I paint over the new sealant?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

How we handle window mastic in Amport
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with gaps left after new windows were fitted and hard, cracked sealant around windows, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Amport is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Common problems we fix in Amport
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
If you can see any of these, it’s time to have the joints looked at:
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
- Cracked or shrunken mastic around the frame
- Mastic that is falling out in pieces
For landlords with property near Grateley station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Which sealant they’ll use, and why
- How much experience the applicator has
- Whether they seal over old material or remove it
- How long to leave it before use
How to look after the new joints
To keep the joints looking good and working properly:
- Do not paint over the silicone
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
- Use gentle cleaners on frames and sealant
Silicone cannot usually be painted, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a few frames, or a day or more for a whole house from start to finish. In a small place like Amport, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- On commercial sites, let us know about site rules

Advice
Windows and doors in Amport
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Amport Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
