Sealant on show in Long Green’s commercial buildings
Less than 3 miles from Long Green there are two named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it. Long Green is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.
Offices and shops close to stations such as Braintree Freeport station (to the west of Long Green) tend to be busy all day, so sealant work is planned around opening hours. For tenants and agents on sites such as Lanham Business Park (0.6 miles east of Long Green), office fit-outs, reception joints and window perimeters are the usual sealant work.
Long Green is about 2 miles south-east of Braintree, in Essex. Across the CM77 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Essex coverage takes in 644 places. There’s a separate page for London, about 39 miles away.

Sealant applicators in Long Green
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the paperwork side is in order: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. If you have external beads that have gone brittle and cracked and frame mastic that has hardened and come away from the wall, we can put it right, on kitchen worktops and splashbacks, washrooms and tea points and window and door perimeters alike. Facilities teams, main contractors and managing agents in Long Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A lot of what we do in Long Green is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
In and around smaller places such as Long Green, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email the details over and we’ll arrange a return visit.

What affects the price in Long Green
To price the job, we consider:
- Site requirements such as inductions and permits
- Travel to remote or island sites
- Whether the work must be split into stages
- Joint width, depth and condition
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- The site address and postcode
- Clear photographs of the problem areas
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Broken glass or blown double-glazed units
- A failed roof covering or waterproofing membrane
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.
What we seal
- Window and door perimeters
- Floor and threshold joints
- Movement joints in walls and floors
- Washrooms and tea points
- Kitchen worktops and splashbacks
- External facade joints
Keeping the joints sound
After handover, these steps help:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Note dates and locations of sealant work for future planning
- On pre-2000 buildings, share the asbestos information before work starts
- Report cracked or peeling sealant early
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks. If anything looks wrong, give us a call on 01277 525 020 or use the quote form with a photo.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to, so sound, smooth joints matter.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
FAQs: Long Green
Is Long Green off your patch?
Not at all. Long Green is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does a hotel in Long Green need to shut while its sealant is renewed?
In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
Is the old sealant taken out first?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.
What guarantee do you give on resealing?
Each job sits under our 12-month guarantee from handover. Keeping joints clean and inspected helps them last well beyond that.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you take on multi-site sealant work?
Yes, we can. Send a list of addresses and what’s needed at each, and we will put together a fixed quote and a sensible order of work.

Related advice
Do you need commercial sealant contractors in Long Green?
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. BS 6213 gives guidance on choosing construction sealants.
It’s worth sending us details if you spot any of the following:
- Sanitary sealant that has gone black and patchy
- Water staining near frames, panels or ceilings
- Layers of sealant, all of them failing
- Wall and floor joints that have lost their seal
Occupiers with premises at both Lanham Business Park and Springwood Industrial Estate could have the sealant at each handled under one quote.
What your quote should include
- How they handle RAMS and site documents
- How the existing material will be dealt with
- Is the sealant right for the movement and the substrate?
- Health and safety accreditation such as CHAS
