Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Warn occupants and staff about the work
- Share your working hours and any access restrictions

Construction mastic in Mile End, done properly
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Mile End, send drawings through our quote form, or phone or email us to talk it through. If you have perimeter gaps outside the sealant’s range and sealant knocked or painted over by other trades, we can help. Most enquiries from Mile End start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Around Mile End, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What affects the price in Mile End
Quotes vary with the job. It mainly depends on:
- Working within restricted access windows
- The total length or number of joints
- Travel to remote or island sites
- Removal of failed or old sealant
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Send us:
- Whether an asbestos survey exists
- The postcode of the building
- Any dates the work must fit around
- Specification clauses that apply
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Questions about Mile End
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Could you schedule work at a campus like Queen Mary University of London for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Do you guarantee new-build sealant work?
It’s backed by our 12-month guarantee, covering how we sealed. Protecting sealed areas from following trades helps avoid damage.
Can you work to our specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What do you charge?
There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Damage to finishes by other trades after we’ve sealed
- Faulty frames rather than failed sealant
- Designing joint widths or choosing the specification (that sits with the designer)
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly before you book.
What we seal
- Brick and block movement joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
Facades, frames and programmes in Mile End
The area within 2 miles of Mile End holds plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. As part of Greater London, Mile End is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Extensions at sites like Mile End Hospital, 0.5 miles west of Mile End, usually sit beside working departments, and the mastic follows strict access rules. On a campus such as Queen Mary University of London, under half a mile to the west of Mile End, new teaching buildings and residences are normally built and refurbished around the academic year.

When to call us in Mile End
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
What tends to prompt an enquiry:
- A mastic package split between trades with no clear owner
- Internal caulk splitting as the building dries out
- Sealant knocked or painted over by other trades
- External joints sealed in damp or cold conditions that are now failing
Projects at colleges like Onelab College, 0.6 miles east of Mile End, tend to run to term dates, so the mastic is planned tightly.
What to look for in a quote

Why it’s worth doing now in Mile End
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. We will say so if a frame itself is the problem. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Flag uneven or tapered frame gaps early
- Keep scrapers and abrasive pads off new beads
- Protect sealed areas from following trades
- Share drawings and the specification as soon as possible
Any damage after we’ve finished should go on the snag list right away. We can return to clear snags before handover as agreed in the quote.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last. We raise them during our first walk of the area.
