Window mastic in Beam Park, done properly
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on timber windows & doors, uPVC windows and window sills, and the jobs we see most are leaking joints at the ends of sills and mastic that has split away from the wall.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Beam Park as anywhere.
Our work is backed for twelve months, in Beam Park and everywhere else we cover.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. In a London area like Beam Park, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

Beam Park questions
Can parking be tricky for a visit in Beam Park?
Parking in Beam Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near Dagenham Dock station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not use solvent cleaners on the joint
- Make sure the drainage slots are not blocked
- Wash the frames with mild soapy water
- Check the mastic once a year
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

When to call us in Beam Park
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Look out for any of the following:
- Gaps between the frame and the inside reveal
- White mastic on grey or black frames
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
Rented homes near Dagenham Dock 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.
What your quote should include

- Are they insured?

Why act early in Beam Park
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Beam Park.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.
Beam Park homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
For an older house near a landmark such as Church of St Helen and St Giles, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Newtons Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
