About our mastic sealing in New England
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Site teams most often ask us about leaks at window and door perimeters and failed external movement joints, across communal kitchens and washrooms, shopfronts below residential blocks and balcony and threshold joints. Searching for sealant specialists in New England? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around smaller places like New England, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What the job involves on each surface

Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
Mastic sealing in New England: the local picture
New England is about 46 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. New England sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first.
Trustees of buildings like Church of St Leonard can bring frame and external mastic into a planned maintenance list. Property owners at sites such as Blois Meadow Business Centre (1.8 miles south-west of New England) can have mastic renewed between lettings.
New England is in Essex. Across the CO9 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Essex coverage takes in 644 places. For work in that direction, see our London page.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Failed window or door frames, which need a window contractor
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Surfaces we seal
- Balcony and threshold joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Building owners, agents and FMs in New England
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like New England are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
- Flag any permit to work we’ll need

Advice
Your questions answered
Can you work at a site such as Blois Meadow Business Centre, by New England?
Yes. Our area takes in New England and its surroundings, with estates and business parks such as Blois Meadow Business Centre included. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can one quote cover a number of our buildings near New England?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Does weather matter for sealant work?
It can, when the joints are outside. 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.
How long does a typical visit take?
It depends on the scope, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you take on resealing for a block portfolio?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
What sets the cost
Each job is priced on its own details. The main factors are:
- Any access equipment needed
- The total length or number of joints
- The product specified
- Backing rod, priming and other preparation
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
- Whether an asbestos survey exists
- The postcode of the building
