Construction mastic in Shelley
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. If you have frame gaps too wide for sealant alone and snag items on joints that need redoing before handover, we can help, whatever the surface. Whoever orders the work in Shelley, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as Shelley is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Building owners, agents and FMs in Shelley
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Shelley are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot
- Tell staff and tenants when we will be in

Construction mastic in Shelley: the local picture
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. At about 21 miles from central London, Shelley is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
With historic properties like Hill Hall, 4.8 miles south-west of Shelley, in the area, refurbishment work often meets old masonry that needs compatible sealants. For contractors at a school such as Ongar Primary School, sealing has to be finished before term starts.

Common problems we fix in Shelley
A new building moves while it dries and settles. Materials lose construction moisture and shrink. Picking a flexible sealant where there’s movement keeps snags down.
Site and facilities staff are often the first to spot these:
- Early adhesion failures on new external joints
- Missed perimeter joints on a new elevation
- A long mastic snag list close to completion
- Bath and shower joints scraped during the final clean
Units on estates such as Hallsford Bridge Industrial Estate (to the south-east of Shelley) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Your questions answered
Is Shelley too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you take on work at healthcare sites like St. Margaret's Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- Phasing around occupants
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Asbestos survey details if the building is older
- The product your specification calls for
- Whether the building will be occupied during the work
- When you need the work done
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Joints damaged after sign-off by following trades
- Joint design decisions that belong to the architect or engineer
- Deciding which fire-stopping product a penetration needs
If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.

Why act early in Shelley
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. We cut out and redo the joint properly. Halls, stores and units around places like Shelley may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
