Construction mastic for commercial buildings in Seven Kings
The specification and the programme set the job rather than whatever product is to hand. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. If you have early adhesion failures on new external joints and missed perimeter joints on a new elevation, we can put it right. A specialist sealant contractor works differently from a general builder: in Seven Kings, that means joint design, primers and backing rod as standard.
Construction in a London area such as Seven Kings means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Common problems we fix in Seven Kings
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Site and facilities staff are often the first to spot these:
- Sealant knocked or painted over by other trades
- Frame gaps too wide for sealant alone
- Early adhesion failures on new external joints
- Snag items on joints that need redoing before handover
For a contractor working at a hospital such as Goodmayes Hospital (0.9 miles north-east of Seven Kings), perimeter and facade sealing is planned around patients and deliveries.
Before you book anyone
- How long is the guarantee, and what does it include?
- Whether their applicators hold CSCS cards
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For a job in Seven Kings, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- Point out any areas we must not close
- For older buildings, check the asbestos register before work
Quotes
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Advice
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Faulty frames rather than failed sealant
- Specifying the product where the designer hasn’t
If you are not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Sanitary and kitchen joints
- Brick and block movement joints
- Window and door perimeters
- Floor and skirting junctions

- Cladding and panel joints
Contractors’ notes for Seven Kings
As part of Greater London, Seven Kings is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are plenty of hotels within about 2 miles of Seven Kings. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
University estates such as University of East London, 3.9 miles to the south-west of Seven Kings, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Hotel extensions and refits, at places such as Former Cauliflower Hotel, which lies south-west of Seven Kings, normally run between busy periods, so the sealing is squeezed into short windows.

Local landmarks in Seven Kings

A little further out are The Brewery (3.6 miles east) and Redbridge Museum (1.2 miles south-west). Not far away are Hainault Lodge and Hollow Pond.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Common questions from Seven Kings clients
Is hospital work, at somewhere like Goodmayes Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you cover business parks and estates near Seven Kings, such as Newbury Retail Park?
Yes. Our area takes in Seven Kings and its surroundings, with estates and business parks such as Newbury Retail Park included. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
How do you work with the site programme?
We work to your programme. Tell us the sequence and we’ll plan applicators around it, sealing as areas become ready.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
What the job involves on each surface
Snagging before handover
Snags typically come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product.
Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Keep finished joints away from paint, plaster and scrapers
- Stick to the specified sealant rather than a generic substitute
- Record the products used in the O&M file
- Ask cleaners to use soft cloths around fresh sealant
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit as agreed in the quote.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
