Commercial sealant contractors in Dedham
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: 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’ll confirm with the quote. We work on kitchen worktops and splashbacks, floor and threshold joints and external facade joints, and the failures we are asked to look at most are leaks that seem to come through a sealant line and hardened, chalky sealant on south-facing or exposed elevations. Facilities teams, main contractors and managing agents in Dedham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
On a typical commercial building in Dedham, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
Commercial sealant work around smaller places like Dedham tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- How much existing material needs removing
- The site’s rules and procedures
- The product specified
- Quantities, in metres or numbers
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- The product your specification calls for
- The site address and postcode
- Clear photos of the problem areas
- Whether the building will be occupied during the work
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Faulty windows rather than failed perimeter sealant
- A dripping trap, valve or pipe behind a fitting
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

When to call us in Dedham
The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade. BS 6213 gives guidance on choosing construction sealants.
It’s worth sending us details if you spot any of the following:
- Layers of sealant, all of them failing
- Water staining near frames, panels or ceilings
- Movement joints packed with grit and debris
- Weathered facade sealant that no longer flexes
Offices at parks like Blue Barns Business Park, 2.4 miles to the south-west of Dedham, have receptions, kitchens and glazed partitions where a tidy joint matters.
Before you book anyone
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
Looking after the joints
To get the most from the new sealant:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Keep washroom and kitchen extraction working
- On pre-2000 buildings, share the asbestos information before work starts
- Keep abrasive pads and scrapers off resealed joints
Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them. Where work has disturbed a joint, just ring 01277 525 020 or email the details over for a quote.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are.
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Smaller jobs around Dedham can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We start with the evidence: photos, drawings or a look on site.
- 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.
Preparing the site
- Let us know about inductions and permits
- Tell us your opening times and when work is allowed
- Send asbestos survey details if the building is pre-2000

Dedham: questions and answers
Is a smaller place like Dedham outside your area?
Not at all. Dedham is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Will our hotel in Dedham need to close for the work?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
What site paperwork can you provide?
We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
What about asbestos in old mastic?
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.
Can you take on work for an FM or managing agent?
Yes. FMs, managing agents and landlords are among our regular clients. We can work to your instruction process and site rules.
Is it OK to apply fresh sealant over existing beads?
Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.

Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
