About our mastic sealing in Tyburn
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on balcony and threshold joints, communal kitchens and washrooms and shopfronts below residential blocks, and what we are called in for most is no planned programme for sealant and damp patches beside frames. Whoever orders the work in Tyburn, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Different surfaces, different methods
Estate-wide resealing programmes
Priority order can follow condition, complaints or your maintenance plan. You get one fixed quote per building or for the whole estate.
Planned maintenance
We can work into your cyclical maintenance plan, building by building.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Advice
For owners and agents in Tyburn
For a London block, the agent or landlord usually handles notices to residents and access to flats. We work to your notice and access plan.
For owners of several units at places like Brompton Cross District Shopping Centre., 1.3 miles to the south of Tyburn, one programme can deal with frame and external mastic across the lot. Student accommodation around universities such as BPP University (to the west of Tyburn) is normally managed block by block, which suits a planned mastic programme. Trustees of buildings like Church of the Annunciation can bring frame and external mastic into a planned maintenance list.
Tyburn is about 1 mile west of City of Westminster, in Greater London. Across the W1H postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places, large and small.
Commercial sites across W1H, W1U and W1K are covered. Streets here include Sussex Square, Oxford Square and Bayswater Road, and sites on any of them can send details for a fixed quote. Access to Tyburn is via the A4209 among other routes, so getting applicators and materials to site is simple. Close to Tyburn, our area also takes in Connaught Village (1 mile north-west), Hyde Park Estate (1 mile north-west), Paddington (1 mile north-west), City of Westminster (1 mile east) and Paddington Green (1 mile north-west).

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Failed window or door frames, which need a window contractor
- Substrate edges that need repairing first
- Glazing that needs replacing
If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer.

Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Group repairs into a planned programme
- Make it easy for occupiers to report draughts
- Have the asbestos survey to hand for older buildings
- Reduce knocks to communal area joints
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
