Questions about Kew
Does your area include sites such as Kew Retail Park, near Kew?
Yes. We cover Kew and the area around it, including industrial estates, business parks and retail parks such as Kew Retail Park. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you quote for a block close to Chiswick station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Do you cover Kew?
Yes. Kew falls within our area, and you can ring 01277 525 020 or send details through our quote form to get started.
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.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
When is resealing likely to be due?
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.
Mastic sealing in Kew
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Kew carry our 12-month guarantee. If you’re dealing with brittle perimeter mastic across a building and open joints in brickwork or panels, we can help, on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks alike. Looking for mastic applicators who cover Kew? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. 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.

Building owners, agents and FMs in Kew
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Building owners and managing agents use us on everything from one building to a spread of sites around Kew. One quote can cover more than one site, so there’s one set of paperwork to deal with.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Misted or failed double-glazed units
- Frames that are rotten, warped or broken
- Leaks from above rather than through a joint
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
Joints and surfaces we work on
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
Cost factors for mastic joints
These are the things that shape the price:
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- The total length or number of joints
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email drawings and photos.

Looking after the joints
After handover, these steps help:
- Have the asbestos survey to hand for older buildings
- Track which buildings were done and when
- Keep bins and bikes away from communal door frames
- Include mastic in your cyclical inspections
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
What we are called out for in Kew
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified it comes away from one face.
Site and facilities staff are often the first to spot these:
- Repeated reactive repairs to the same buildings
- Movement joints with sealant missing
- The same joint failures repeated across a portfolio
- Old repairs sealed over failed mastic
Buildings close to stations like Chiswick station, 0.5 miles to the south-east of Kew, are often flats over shops, with frame mastic to keep sound.
What your quote should include
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- The terms of the workmanship guarantee
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. In Kew, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We inspect each building and record the joints that have failed.
- 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.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
