Construction mastic in East Ham, done properly
We work to the specification and the programme. Where the specification names a product, we use it; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. The enquiries we see most involve a mastic package split between trades with no clear owner and frame perimeters left unsealed or poorly sealed, across cladding and panel joints, floor and skirting junctions and window and door perimeters. Facilities teams, main contractors and managing agents in East Ham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about East Ham
Do you take on jobs in East Ham where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Could you schedule work at a campus like University of East London for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is East Ham in your area?
Yes. We cover East Ham and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or email drawings and photos.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Can you fit around our programme?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. 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.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Let building users know which areas are affected
- Share the asbestos register for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Construction mastic around East Ham: points for this area
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in East Ham. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of East Ham holds plenty of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Work at a hotel such as Barking Hotel (to the north-east of East Ham) tends to be programmed around bookings, mastic included. University estates such as University of East London (0.9 miles west of East Ham) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
East Ham is about 5 miles south-east of Walthamstow, in Greater London. Across the E6 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. East Ham is one of 764 places in Greater London on our list. We also cover London, some 7 miles away.

How the job changes by surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product and hygienic or food-safe grades wherever food contact is possible.
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
After the work
After handover, a little attention goes a long way:
- Check frame gaps are within the sealant’s range before sealing
- Brief the final clean team to avoid blades near sealant
- Note which sealant went where at handover
- Release areas for mastic once other trades have finished in them
Record which products went where in the handover file. That helps the building owner maintain the joints later. Tell us what records you need and we’ll confirm with the quote.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
When to call us in East Ham
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.
Things that typically lead to an enquiry:
- Oversized or tapered gaps around new frames
- Existing joints on a refurb that need cutting out and resealing
- Caulk cracking where joints are moving more than expected
- Window and door perimeters that won’t pass inspection
On a healthcare site such as Newham University Hospital, 1 mile to the south-west of East Ham, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
