Mastic sealing near Hounslow
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. 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.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- 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
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Warn occupants and staff about the work

Mastic sealing in Hounslow, done properly
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. If you are dealing with the same joint failures repeated across a portfolio and window mastic that has split and shrunk, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hounslow is the same: the right product in a properly prepared joint.
For managing agents in Hounslow, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Leave it or put it right?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish and one 12-month guarantee. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Broken glass or failed sealed units
Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Include mastic in your cyclical inspections
- Check the asbestos register before any old mastic is disturbed
- Track which buildings were done and when
- Look at the sunniest and most exposed elevations first
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
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.
Hounslow: questions and answers
Do you work for managing agents with blocks near Hounslow station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Can you work at a site such as Inwood Business Park, by Hounslow?
Yes. Estates, retail parks and business parks around Hounslow, Inwood Business Park among them, are all within reach. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Do you cover Hounslow?
Yes. We cover Hounslow, and you can ring 01277 525 020 or email a schedule or drawings to get started.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Different surfaces, different methods
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
