Construction mastic in Eel Pie Island, done properly
Mastic tends to be one of the final packages before handover, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers, following the trades through the building as rooms and elevations become ready. Site teams most often ask us about existing joints on a refurb that need cutting out and resealing and frame gaps too wide for sealant alone, across sanitary and kitchen joints, cladding and panel joints and window and door perimeters. Looking for mastic applicators who cover Eel Pie Island? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to call us in Eel Pie Island
On construction sites, joints typically fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
Clients typically get in touch after noticing one or more of the following:
- Existing joints on a refurb that need cutting out and resealing
- A mastic package split between trades with no clear owner
- Mastic snags holding up handover
- Internal caulk splitting as the building dries out
New wings at hospitals like Cassel Hospital (to the south-east of Eel Pie Island) bring long runs of window and panel joints to seal.

Questions about Eel Pie Island
Could you schedule work at a campus like St Mary's University for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Cassel Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you work plot by plot or floor by floor?
Our work is sequenced around the programme. Areas are sealed as they’re released by the site team.
What accreditations do you hold?
CHAS and Constructionline are both in place, and each applicator is CSCS-carded. Public liability insurance is in place.
How long does a typical visit take?
That varies with the scale of the job, but the work normally takes whatever the programme allows, since the work follows the trades as areas are released. For bigger or phased jobs, we will set out a timescale with the quote.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
From enquiry to sign-off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. In Eel Pie Island, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected
- Point out parking and an unloading spot
- Agree which areas must stay open

When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Quoting for work in Eel Pie Island
These are the things that shape the price:
- Induction, permit and paperwork requirements
- The product specified
- Quantities, in metres or numbers
- Travel to remote or island sites
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Sending details for a quote
We can often quote from photographs and a few details. Please tell us:
- What the building is and how it’s used
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- Your programme or deadline
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Why deal with it now?
A quick bead over a damaged joint can get an area past inspection, but it won’t last. 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. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
