Commercial sealant contractors across CO3: what to expect
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. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. We work on movement joints in walls and floors, kitchen worktops and splashbacks and window and door perimeters, and the usual reasons a site gets in touch are leaks that seem to come through a sealant line and sanitary sealant that has gone black and patchy.
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations, or we arrange a site visit.
- Next comes a diagnosis and a fixed quote.
- Before anything is cut out, we agree access, timings and sequence.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
What you will pay
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What you get with us
- Coloured sealants to suit the setting, where available
- CHAS accredited
- A Constructionline member, so easy to vet
- Work to your specification and the manufacturer’s guidance

Local landmarks in Camulodunum

Other local landmarks include Lexden Park (less than half a mile north-west) and The Sun Inn (0.6 miles north-west). The closest station to Camulodunum is Colchester Town station, roughly 1.4 miles east. A little further out are Lion Walk (1.2 miles east) and Colchester Castle (1.4 miles east). The countryside around Camulodunum includes Lexden Gathering Grounds.
Commercial premises across CO3
The commercial stock in CO3 mixes older town-centre buildings with newer offices and units, in places such as Colchester, Camulodunum and Lexden and beyond. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, and every job in CO3 starts with access, parking and site rules.
Camulodunum: Shops and cafés around stations like Colchester Town station (to the east of Camulodunum) trade from early, so work is timed around them. A business with units at Colchester Retail Park and Gosbeck's Business Park needn’t use two contractors for its sealant.
Why deal with it now?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Resealing while only the sealant has failed keeps the job small.
Comparing quotes
- Health and safety accreditation such as CHAS
- The named product and why it was chosen
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
Why it fails
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 will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.
These are often picked up first by site or facilities staff:
- Expansion joints with the sealant torn out
- External beads that have gone brittle and cracked
- Black mould through washroom sealant that won’t clean off
- Window and door perimeter joints that have cracked open
After the work
After handover, a little attention goes a long way:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Put external and wet-area joints on a regular inspection round
- On pre-2000 buildings, share the asbestos information before work starts
- Keep a record of which joints were resealed and when
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.
Surface by surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. We plan around the access windows the store gives us, working in sections where that helps.
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Close-up photos or a site visit tell us what’s needed.
How the quote is worked out
We price every job individually. The things that drive the figure:
- Any access equipment needed
- Which sealant the job calls for
- Site requirements such as inductions and permits
- 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.
What to include in your enquiry
However big the job, these details speed things up:
- A wide shot and a close-up of the area
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- The product your specification calls for
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or email us.
FAQs: CO3
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you check for asbestos before removing sealant?
It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How do you keep disruption to occupiers down?
That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we’ll work around it.
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.
Can you take on work for an FM or managing agent?
Yes. You can send details through our quote form, and we will confirm any paperwork you need with the quote.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
