Surface by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Leave it or put it right?
Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Walter's Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Keep jet washers away from the mastic
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes most of a day for a typical house, less for a few frames, and the area is left clean. In a small place like Walter's Green, access is usually 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.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive

What should I tell you?

Do the sealants smell?

Can you match the sealant to my frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Window mastic in Walter's Green: local notes
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. Historic houses like Penshurst Place (about 2.1 miles north-east) are a reminder that the area around Walter's Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Ashurst Kent station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Peter, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Fordcombe Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
