DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What else we do in Homerton
Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Homerton, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will go through it with you.
What you get with us
- Neat joints and a tidy finish
- We never seal over old sealant
- Approved under the ARBOMaster scheme
- Sealant colour chosen to suit

Window mastic in Homerton: local notes
Historic houses like Sutton House (about 0.3 miles south-west) are a reminder that the area around Homerton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homerton is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Schools such as Rushmore Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Your questions about window mastic in Homerton
Can you do window mastic in Homerton?
Yes, Homerton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is parking an issue for window mastic in Homerton?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Are you fully insured?
Yes. Full insurance covers our work.
How do I get a quote for window mastic in Homerton?
Size, access and the old material all affect the cost. Call for a quick quote.
Can I paint over the new sealant?
Not usually, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
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.
What we’re called out for in Homerton
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Keep an eye out for these signs:
- Sealant in the wrong colour for the frame
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Cold air getting in at the frame edge
In the older streets around United Reformed Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Whether the sealant suits the joint
- Is VAT in the price?
- Is the old sealant removed completely?
- Which colour the sealant will be
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are. In a London area like Homerton, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work
How to get a quote
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or drop us an email and describe the job, and photos are welcome.

Keeping the joints in good condition
Aftercare is simple:
- Clear any debris from frame drain holes
- Ventilate rooms so frames don’t stay wet inside
- Clean frames with a soft cloth and soapy water
- Repaint timber before it’s bare
Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
