Sealant applicators in Graffham
Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. We work on floor and threshold joints, movement joints in walls and floors and external facade joints, and the usual reasons a site gets in touch are black mould through washroom sealant that won’t clean off and external beads that have gone brittle and cracked. Most enquiries from Graffham start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
On a typical commercial building in Graffham, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Work in smaller places such as Graffham tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
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 are clear about what is covered before work starts.

Why it’s worth doing now in Graffham
Reactive resealing, a leak at a time, tends to cost more overall than a plan. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We’ll suggest an order, worst sealant joints first. One visit to deal with every failing joint makes more sense than several trips to a place like Graffham. Send photographs of each area and we will quote for the lot.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Why appoint us
- A range of standard colours, depending on the product
- Matching to RAL references, product permitting
- Our applicators hold CSCS cards
- Joints cleaned back to sound surfaces

Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Work for main contractors and building owners
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
We work for building owners and managing agents on everything from one building to a spread of sites around Graffham. One quote can cover more than one site, which keeps the paperwork simple.
Common questions from Graffham clients
Which documents can you supply for work in Graffham?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Can you supply sealant in our brand colour for a site in Graffham?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you work in Graffham?
Yes. We cover Graffham, and you can phone 01277 525 020 or send photos by email to get started.
What about asbestos in old mastic?
We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility.
What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Old mastic that tests positive for asbestos
- Leaks from pipework, wastes or valves (that’s plumbing)
- Faulty windows rather than failed perimeter sealant
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
Joints and surfaces we work on

How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from part of a day on a short run of joints to several weeks on a large phased package, and we clear our waste as we work. If others near Graffham need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We start with the evidence: photos, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Send your site hours and access windows
- Point out any areas we must not close
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Advice
Frontages, fit-outs and joints in Graffham
Graffham is in the South East, one of the UK’s drier regions. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Graffham lies roughly 46 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. If you have premises across the region, one contractor can cover them all.
A lasting commercial joint around Graffham begins with the old bead fully out and the faces clean and dry.

Signs you need commercial sealant contractors in Graffham
Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants.
Common reasons buildings call us in:
- Messy, uneven beads from earlier work that let the building down
- Damp patches where an external joint has failed
- Window and door perimeter joints that have cracked open
- Movement joints packed with grit and debris
Where a joint is on show in Graffham, we’ll check which shades the product offers before work starts.
What your quote should include
