When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Leaks from above rather than through a joint
- Failed window or door frames, which need a window contractor
- Asbestos-containing sealant, which we don’t remove
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

How we handle mastic sealing in Hayes
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you are dealing with draughts at frames across a block and repeated reactive repairs to the same buildings, we can help, on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms alike. Looking for mastic applicators who cover Hayes? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Across Greater London, Hayes included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: Hayes
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Do you work for managing agents with blocks near Hayes & Harlington station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Do you work in Hayes?
Yes. We take on work across Hayes.
What the job involves on each surface
Communal areas
We keep entrances and stairs open throughout. We work in sections so access is never blocked.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.
Common problems we fix in Hayes
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Things that normally lead to an enquiry:
- Movement joints with sealant missing
- Draughts at frames across a block
- Leaks at window and door perimeters
- Patchy repairs in mismatched sealant
Landlords with units on estates such as Caxton Trading Estate, 0.5 miles to the south of Hayes, can bring frame, door and external mastic across several units into one programme.
Questions to ask before you book
- The named product and why it was chosen
- Who will actually carry out the work
- Proof of insurance
- How they’ll work around occupants
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in Hayes can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Share the asbestos register for older buildings
- Send any specification or drawings in advance
Quotes
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or email us with what you know.

Aftercare for building managers
After handover, these steps help:
- Ask residents or tenants to report leaks and draughts early
- Have the asbestos survey to hand for older buildings
- Keep a record of when each building was resealed
- Check sealant joints during planned building inspections
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Quoting for work in Hayes
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The total length or number of joints
- Location, for remote and island sites
- Access and working height
- The product specified
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.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- A wide shot and a close-up of the area
- Your programme or deadline
For a fixed quote, speak to us on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
