Sealant applicators in Sudbury
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. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on external facade joints, kitchen worktops and splashbacks and movement joints in walls and floors, and the usual reasons a site gets in touch are black mould through washroom sealant that won’t clean off and damp patches where an external joint has failed. A single leaking joint is often how a building in Sudbury first comes to us: we look at the rest while we are there and tell you what we find.
Quotes for commercial sealant in Sudbury can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Which sealant the job calls for
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
- Whether the work must be split into stages
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Good information means a firmer quote. When you get in touch, include:
- How the joints are reached, and at what height
- The postcode of the building

- The asbestos register, for older buildings
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over if you’d rather talk the job through.

Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are 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. In Sudbury, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
Before we start on site
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we will be in

Your questions answered
Must a hotel around Sudbury close while you work?
In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Is Greenford Green Business Park, near Sudbury, within your area?
Yes. Estates, retail parks and business parks around Sudbury, Greenford Green Business Park among them, are all within reach. Photos and a short description are enough for a first look.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How many days will you need on site?
It depends on the scope, but the work normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you work for facilities managers and managing agents?
Yes. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.
Is Sudbury in your area?
Yes. Sudbury falls within our area, and the simplest way to start is to call the office on 01277 525 020 or send photos by email.
Common problems we fix in Sudbury
No sealant joint is permanent. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together.
Look out for the following:
- Earlier reseals applied straight onto the failed bead
- Mouldy silicone around WCs, urinals and vanity tops
- Weathered facade sealant that no longer flexes
- Shrunken sealant along kitchen worktops and splashbacks
Offices at parks like Greenford Green Business Park (1.1 miles south-west of Sudbury) have receptions, kitchens and glazed partitions where a tidy joint matters.

Site staff or a sealant specialist?
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.
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- A failed roof covering or waterproofing membrane
- Misted, cracked or failed glazing units (a glazier’s job)
- Structural cracks or movement the joints weren’t designed for
If you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- Movement joints in walls and floors
- External facade joints
- Floor and threshold joints
- Kitchen worktops and splashbacks
- Washrooms and tea points
