Frames and glazing around Oad Street
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.
Homes close to Church of St Peter and St Paul include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Newington station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How we handle window mastic in Oad Street
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on uPVC windows, window sills and timber windows & doors, and the jobs we see most are cracked sealant at the sill ends and untidy mastic left by window fitters.
Around Oad Street, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Why it’s worth doing now in Oad Street
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around Oad Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Oad Street: your questions answered
Can you do window mastic in Oad Street?
Yes. Our work covers London and the South East, and Oad Street is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Newington station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check the mastic once a year
- Paint up to the joint, not over it
- Use gentle cleaners on frames and sealant
- Avoid harsh chemicals near the mastic
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
How it works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house in most cases. Somewhere as small as Oad Street, access is often the only tricky part. 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.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

Signs you need window mastic in Oad Street
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
The problems people generally mention when they call are:
- Cracked or shrunken mastic around the frame
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- White mastic on grey or black frames
Schools such as Borden Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
