Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- How accessible the joints are
- The product specified
- The size and state of each joint
- Travel to remote or island sites
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Drawings or a marked-up plan, if available
- Specification clauses that apply
- When you need the work done
- Whether the building will be occupied during the work

How we handle construction mastic in Heyshott
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers, sealing plot by plot or floor by floor as areas are released. We work on window and door perimeters, brick and block movement joints and sanitary and kitchen joints, and what we’re called in for most is bath and shower joints scraped during the final clean and oversized or tapered gaps around new frames. Searching for sealant specialists in Heyshott? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Construction in and around smaller places such as Heyshott is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Do you need construction mastic in Heyshott?
A new building moves while it dries and settles. Materials lose construction moisture and shrink and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
Site and facilities staff are often the first to spot these:
- Frame gaps too wide for sealant alone
- Mastic snags holding up handover
- Bath and shower joints scraped during the final clean
- A mastic package split between trades with no clear owner
New units and refits on sites such as Holmbush Industrial Estate (to the north-west of Heyshott) need their panel and perimeter joints sealed to the specification.

Honest limits
Some faults sit outside our scope, and we say so rather than covering them up:
- Deciding which fire-stopping product a penetration needs
- Glazing units that are cracked or misted
- Specifying the product where the designer hasn’t
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think.

- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.

Related advice
Why act early in Heyshott
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. Converted and older buildings near places like Heyshott tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Don’t force external sealing on a damp or frosty day
- Ask for joint and product checks before the package is urgent
- Check frame gaps are within the sealant’s range before sealing
- Keep product details for future maintenance
After we have 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.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
Questions we are asked in Heyshott
Is Heyshott too far out for you?
Not at all. Heyshott is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Would you work within a site like Midhurst Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Do your applicators hold CSCS cards?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
How do I request a quote?

Mastic packages on Heyshott sites
At about 46 miles from central London, Heyshott is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Heyshott included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
Historic houses such as Cowdray House (to the north of Heyshott) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. On a healthcare site such as Midhurst Community Hospital (2.9 miles north of Heyshott), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Heyshott is about 8 miles north of Chichester, in West Sussex. Businesses, contractors and managing agents in Heyshott use us for work on mastic packages. 373 places across West Sussex fall within our area, including Heyshott. Sites around Portsmouth have their own page, roughly 19 miles from Heyshott.
