Sealant specialists in East End
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. 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 washrooms and tea points, movement joints in walls and floors and external facade joints, and the usual reasons a site gets in touch are window and door perimeter joints that have cracked open and expansion joints with the sealant torn out. Whether you call it commercial sealant work, mastic application or joint sealing, the work in East End is the same: the right product in a properly prepared joint.
The most common commercial job in East End is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
Work in smaller places such as East End tends to come one building at a time: a pub kitchen, a hall, a small office. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.
A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we’ll come back to it.

Common questions from East End clients
Is East End too far out for you?
No. Places such as East End are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Does a coastal location like East End affect which sealant is used?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you supply RAMS and insurance details?
We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What do you need from us to quote?
Send what you have, even a few photographs and rough lengths. We follow up with questions or a visit where needed, then a fixed quote.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- The postcode of the building
- The product your specification calls for
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
What the job involves on each surface
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps, so we’ll flag it if the detail needs a different product.
Facade and cladding joints
Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near East End need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
- We work out why the joints have failed and fix a quote for the agreed scope.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Before we start on site
- Tell us what induction or permit system the site runs
- Send asbestos survey details if the building is pre-2000
- Move anything stored against the joints
Ask for a quote
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Advice

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Have extract fans checked so wet areas dry out
- Keep barriers up until the new sealant has cured
- Brief cleaning contractors to avoid scourers and blades on sealant
- Deal with small splits before they become leaks
Keep an eye out for other trades after we’ve gone. Shop refits, new services and replaced fittings often break the seal around them. If that happens, speak to us on 01277 525 020 or send photos by email and we will price putting it right.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, so sound, smooth joints matter.
What we are called out for in East End
In wet areas the enemy is normally mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant; when mould is in the body of the sealant, no cleaner will shift it. The fix is a new bead of anti-mould sanitary silicone.
Look out for the following:
- Frame mastic that has hardened and come away from the wall
- Messy, uneven beads from earlier work that let the building down
- Sanitary sealant that has gone black and patchy
- Damp patches where an external joint has failed
If you have premises on more than one site, say at Brantham Mill Industrial Estate and Manor Farm Business Centre, one contractor and one quote can cover both.
What to look for in a quote

- How the existing material will be dealt with

Shops, offices and hotels in and around East End
East End is within about 2 miles of the coast. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. Sea-facing elevations are typically where failed joints show first. Two named trading, business or retail sites lie within about 3 miles of East End. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints, often in a colour the occupier specifies.
On estates like Brantham Mill Industrial Estate, which lies south-west of East End, the office and welfare end of each unit has its own sealant to maintain. Shops and cafés around stations like Manningtree station, 1.8 miles south of East End, trade from early, so work is timed around them.
