Construction mastic in Hextable
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Hextable, send drawings and the specification through our quote form. If you’re dealing with sealant knocked or painted over by other trades and a mastic package split between trades with no clear owner, we can help. A single leaking joint is often how a building in Hextable first comes to us: we look at the rest while we are there and tell you what we find.
In a smaller place such as Hextable, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- Distance, for remote addresses
- Which sealant the job calls for
- Any access equipment needed
- Backing rod, priming and other preparation
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- The postcode of the building
- Specification clauses that apply
- Approximate linear metres or a joint schedule
- Whether an asbestos survey exists
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or email us with what you know.

Questions we’re asked in Hextable
Can you work around term dates at a campus such as University of Greenwich?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Hextable too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Do you guarantee new-build sealant work?
The work is guaranteed for 12 months on the workmanship. Keeping other trades off finished joints prevents most problems.
Can you clear a mastic snag list before handover?
Yes. We can work through a mastic snag list area by area before handover, cutting out damaged or poor joints and resealing them.
How much does the work cost?
Every job gets its own fixed quote. For yours, phone 01277 525 020 or email drawings and photos with a description of the work.
Do your applicators hold CSCS cards?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. We’re also fully insured, with five million pounds of public liability cover.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Why act early in Hextable
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility and a consistent finish. Small buildings around Hextable suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Why appoint us
- CHAS accredited contractor
- One phone line for London, the South East and Scotland
- A range of standard colours, depending on the product
- 12-month guarantee on workmanship
Other services in Hextable
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Mastic packages on Hextable sites
Rainfall across the South East, Hextable included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Hextable has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
New units and refits on sites such as Pembroke Business Centre (0.7 miles south-west of Hextable) need their panel and perimeter joints sealed to the specification. Hotel extensions and refits, at places such as Rowhill Grange Hotel & Utopia Spa, 0.5 miles to the north-east of Hextable, normally run between busy periods, so the sealing is squeezed into short windows. Further education sites such as North Kent College, 1.7 miles north-east of Hextable, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Hextable is about 3 miles south-west of Dartford, in Kent. Commercial clients in Hextable use us for work on mastic packages. Hextable is one of 931 places in Kent on our list. Sites around London have their own page, about 13 miles away.

Further afield, our area takes in Dartford (3 miles north-east), Sevenoaks (9 miles south), Gravesend (9 miles east), Tonbridge (15 miles south), Northfleet (7 miles east) and Kings Hill (14 miles south-east).

When something else is needed
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Joints damaged after sign-off by following trades
- Joint design decisions that belong to the architect or engineer
- Frames fitted out of tolerance
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly.
