Block-wide mastic in Woodlands
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We work to your notice and access plan.
Trustees of buildings like Church of St Mary the Virgin can bring frame and external mastic into a planned maintenance list. For a school such as Spring Grove Primary School, perimeter mastic on windows and doors is a holiday job.

About our mastic sealing in Woodlands
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. Site teams most often ask us about damaged joints in communal entrances and corridors and complaints coming in block by block, on communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Woodlands is the same: the right product in a properly prepared joint.
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, which is why block-wide programmes make sense.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When to call us in Woodlands
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
These are often picked up first by site or facilities staff:
- Damp patches beside frames
- Worn sealant at communal door frames
- Complaints coming in block by block
- Brittle perimeter mastic across a building
Student accommodation around universities such as University of London (to the north-east of Woodlands) is normally managed block by block, which suits a planned mastic programme.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Their approach to joint depth and backing
- Is the sealant right for the movement and the substrate?
- Will CSCS-carded applicators be on site?
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Questions about Woodlands
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Will you take on a block within reach of Isleworth station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
What about access for upper-floor joints?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
Is Woodlands in your area?
Yes. We cover Woodlands, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or send photos by email.
Can you plan resealing across several buildings?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Failed window or door frames, which need a window contractor
- Masonry that has broken away beside the joint
- Broken glass or failed sealed units
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Where we work in Woodlands
- Communal kitchens and washrooms
- Balcony and threshold joints
- Communal entrances and stairwells
- External wall and movement joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
What the job involves on each surface
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Track which buildings were done and when
- Make it easy for occupiers to report draughts
- Share the asbestos register when you send details
- Mention RAMS, insurance or CSCS requirements up front
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
From enquiry to sign-off
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Have the specification and drawings to hand

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
