FAQs: Feltham
Is a hospital such as Ashford Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does your area include sites such as Maple Industrial Estate, near Feltham?
Yes. Our area takes in Feltham and its surroundings, with estates and business parks such as Maple Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How long will the joint resealing take?
Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote, including any phasing.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
About our expansion joint sealing in Feltham

Searching for sealant specialists in Feltham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Feltham, as everywhere in London, access, loading and the ULEZ all come into the plan.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Cracking or settlement that calls for an engineer’s assessment
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Joints too narrow for the movement, which need redesigning by the engineer
If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Traffic, movement and joints around Feltham
The 3 miles around Feltham take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards typically have to keep running, so the work is broken into short sections agreed with the building manager.
Estates like Maple Industrial Estate (0.5 miles south of Feltham) combine warehouse slabs, yards and loading bays, all with joints under wheels. Another example is Felthambrook Industrial Estate, 0.7 miles south-east of Feltham, where floors and yards would be done in stages around the occupiers.
Feltham is about 6 miles south-west of Ealing, in Greater London. Any commercial site in Feltham is covered, for single jobs and planned programmes alike. We work across 764 places in Greater London, from busy centres to rural villages. London is covered too, some 14 miles away.
Anyone looking for expansion joint sealing in TW14 and TW13 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. For a building on High Street, Railway Terrace and Sandycombe Road or nearby, send details and we’ll quote for movement joints.

Further afield, our area takes in London (14 miles east), City of Westminster (12 miles east), Marylebone (12 miles north-east), Kensington (10 miles east), St Pancras (14 miles north-east) and Shoreditch (15 miles east).

Do you need expansion joint sealing in Feltham?
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Typical triggers for a call:
- Debris jammed in movement joints
- Torn sealant in brick or block movement joints
- Car park joints leaking onto vehicles below
- Brittle, chalky sealant on external joints
Hospitals like Ashford Hospital (to the west of Feltham) have multi-storey or surface car parks whose joints carry vehicles round the clock.
What to look for in a quote
- Their pre-qualification and accreditations
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
- Whether their applicators hold CSCS cards
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Planning a London job such as one in Feltham starts with access. Send the building rules and access times with your enquiry.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Make sure the joints can be reached
- Tell staff and tenants when we’ll be in
- Share the asbestos register for older buildings

Advice
What else we do in Feltham
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Any access equipment needed
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- Whether the work must be split into stages
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
However big the job, these details speed things up:
- Any specification or named product
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- Photos of the joints, close up and from further back
