Construction mastic in Plaistow, done properly
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. The enquiries we see most involve perimeter gaps outside the sealant’s range and external joints sealed in damp or cold conditions that are now failing, across sanitary and kitchen joints, cladding and panel joints and internal decorators’ caulk. Most enquiries from Plaistow start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Plaistow must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Keeping the joints sound
After handover, these steps help:
- Stick to the specified sealant rather than a generic substitute
- Record the products used in the O&M file
- Release areas for mastic once other trades have finished in them
- Flag uneven or tapered frame gaps early
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Move anything stored against the joints
- Flag any permit to work we’ll need
Getting a fixed quote
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, photographs and a description will do.
Advice
Plaistow: questions and answers
Can you take on a job at a hospital such as Sloane Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you take on work at estates like Chartwell Business Centre, close to Plaistow?
Yes. Our area takes in Plaistow and its surroundings, with estates and business parks such as Chartwell Business Centre included. A few photos and the unit address let us price the work.
What will the job cost?
We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
How long does a job like this take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Leave it or put it right?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal. We will say so if a frame itself is the problem. Getting scaffold, permits or access booked in Plaistow takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Oversized gaps that need packing or adjustment by others
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly.
Surfaces we seal
- Floor and skirting junctions
- Window and door perimeters
- Brick and block movement joints
- Internal decorators’ caulk
- Cladding and panel joints
- Sanitary and kitchen joints

What else we do in Plaistow
Signs you need construction mastic in Plaistow
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
What tends to prompt an enquiry:
- Internal caulk splitting as the building dries out
- Mastic snags holding up handover
- Oversized or tapered gaps around new frames
- Sanitary sealant damaged by following trades
Further education sites such as Hadlow College (to the north-east of Plaistow) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- The terms of the workmanship guarantee
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
Different surfaces, different methods
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, normally a low-modulus neutral-cure silicone and set the depth with backing where needed.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control.
