Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
For the best life from the joints:
- Note dates and locations of sealant work for future planning
- Look at the sealant around anything that has been moved or replaced
- Make sure contractors see the asbestos survey before cutting out old mastic
- Make sure ventilation in wet areas is switched on and working
Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just call 01277 525 020 or email drawings and photos for a quote.
Sealant installed at the same time typically fails in sequence. A few splits this year usually mean more next year so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.
Commercial sealant contractors in North Waltham
We have applied sealant on commercial sites for over 20 years, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. If you have window and door perimeter joints that have cracked open and water staining near frames, panels or ceilings, we can help. A single leaking joint is often how a building in North Waltham first comes to us: we look at the rest while we’re there and tell you what we find.
In North Waltham, as anywhere, the first joints to go are normally the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
In and around smaller places such as North Waltham, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Structural cracks or movement the joints weren’t designed for
- Leaks from pipework, wastes or valves (that’s plumbing)
- Misted, cracked or failed glazing units (a glazier’s job)
If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer.
What we seal
- Kitchen worktops and splashbacks
- External facade joints
- Washrooms and tea points
- Floor and threshold joints
- Window and door perimeters
- Movement joints in walls and floors
What affects the price in North Waltham
Your fixed quote is built from the real scope. It allows for:
- Phasing around occupants
- Which sealant the job calls for
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Whether the building will be occupied during the work
- Specification clauses that apply
- Anything awkward about access or site hours
- When you need the work done
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Common questions from North Waltham clients
Which documents can you supply for work in North Waltham?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Is a smaller place like North Waltham outside your area?
No. Places such as North Waltham are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Does commercial sealant work come with a guarantee?
Each job sits under our 12-month guarantee, starting at sign-off. Keeping joints clean and inspected helps them last well beyond that.
How is commercial sealant work priced?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What happens if it’s left?
Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation, which is where the lasting value is. Converted and older buildings near places like North Waltham tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Our process
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near North Waltham need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.
Before we start on site
- Confirm the product named in the specification
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
Get a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
