Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Keeping the joints sound
A few simple habits keep the new joints working:
- Ask for joint and product checks before the package is urgent
- Bring the mastic contractor in after the last trades are through
- Record the products used in the O&M file
- Use the product the specification names
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
How we handle construction mastic in Swanton
We work to the specification and the programme. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. If you have cracks opening in caulked internal joints and oversized or tapered gaps around new frames, we can put it right, on cladding and panel joints, window and door perimeters and brick and block movement joints alike. Facilities teams, main contractors and managing agents in Swanton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Swanton, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Your questions answered
Is Swanton too far out for you?
No. Places such as Swanton are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is a hospital such as Maidstone Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is the mastic package guaranteed?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we’ve finished isn’t covered.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What will the job cost?
Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or send photos by email.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Why act early in Swanton
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. We cut out and redo the joint properly. Halls, stores and units around places like Swanton may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
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’ll have a fixed figure to work with.

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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.
Contractors’ notes for Swanton
Swanton sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. Swanton lies roughly 26 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
With historic properties like Old Soar Manor (1.5 miles west of Swanton) in the area, refurbishment work often meets old masonry that needs compatible sealants. New units and refits on sites such as The Alders Industrial Estate (to the south-east of Swanton) need their panel and perimeter joints sealed to the specification.

What we are called out for in Swanton
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
What tends to prompt an enquiry:
- Sanitary sealant damaged by following trades
- Different trades sealing to different standards
- A long mastic snag list close to completion
- Frame perimeters left unsealed or poorly sealed
For contractors at a school such as Mereworth Community Primary School, sealing has to be finished before term starts.
What your quote should include
- Their plan for phasing and protecting the area
- What level of public liability insurance do they hold?
- Health and safety accreditation such as CHAS
- Is the sealant right for the movement and the substrate?
What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Oversized gaps that need packing or adjustment by others
- Faulty frames rather than failed sealant
- Damage to finishes by other trades after we’ve sealed
Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.
