Mastic sealing in Plaistow, done properly
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. If you are dealing with open joints in brickwork or panels and patchy repairs in mismatched sealant, we can help, on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks alike. Looking for mastic applicators who cover Plaistow? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
For managing agents in Plaistow, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
Every job we finish is backed by a 12-month workmanship guarantee, in Plaistow as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Building owners, agents and FMs in Plaistow
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
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.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Plan resealing building by building rather than complaint by complaint
- Start inspections with the most exposed faces
- Keep a record of when each building was resealed
- Make mastic part of routine maintenance checks
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.
One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
FAQs: Plaistow
We manage a building near Sundridge Park station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. Planning a London job such as one in Plaistow starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Preparing the site
- Point out any areas we must not close
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints
Quotes
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
