Commercial sealant contractors across RM9: what to expect
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in RM9. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. We work on floor and threshold joints, window and door perimeters and washrooms and tea points, and what we are called in for most is sanitary sealant that has gone black and patchy and frame sealant that has cracked, shrunk or pulled away.
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.

Local landmarks in Becontree
We work on buildings around Robert Clack School, Parsloes Park and St Joseph's Catholic Primary School and the streets around them. Nearby too are St George's (under half a mile south-east) and Eastbrook pub (0.9 miles east). Becontree’s nearest station is Chadwell Heath station, about 1.5 miles north-west. Other landmarks nearby include Redbridge Museum (3 miles west) and The Brewery (2.4 miles north-east). Not far away are Dagenham Village Churchyard.
Shops, offices and hotels in RM9
The commercial stock in RM9 mixes older town-centre buildings with newer offices and units, in places such as Barking, Dagenham and Becontree and beyond. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
The South East is one of the UK’s drier regions, but external sealing in RM9 still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up.
Becontree: Access in Becontree needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. On a business park such as Business Centre, 0.9 miles north-east of Becontree, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.
Why act early?
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement.

Aftercare for building managers
A few simple habits keep the new joints working:
- Note dates and locations of sealant work for future planning
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Make sure ventilation in wet areas is switched on and working
- On pre-2000 buildings, share the asbestos information before work starts
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint, so we confirm it for each area at handover. Leaving the area closed until then keeps the bead neat.
Sealant rarely fails all at once across a building. A few splits this year normally mean more next year. We can assess the lot and suggest what to do now and later.
Surface by surface
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we will plan around them, working in sections where that helps.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- How much existing material needs removing
- The total length or number of joints
- Working within restricted access windows
- Site requirements such as inductions and permits
A quote for sealant joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- Whether the building will be occupied during the work
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Faulty windows rather than failed perimeter sealant
- Water from a services leak rather than a joint
- Suspect materials that need testing and specialist removal
Questions about RM9
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Does commercial sealant work come with a guarantee?
A 12-month guarantee covers the workmanship, starting at sign-off. Looking after the joints as we advise helps them last.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Can areas stay open during the work?
That comes down to planning: areas are phased, access windows agreed and enough washrooms or entrances left in use. Tell us what has to stay open and we will plan the job around it.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you take on work for an FM or managing agent?
Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. Tell us how you issue work and we’ll fit in.
