Seven Kings: questions and answers
Does your area include sites such as Newbury Retail Park, near Seven Kings?
Yes. Our area takes in Seven Kings and its surroundings, with estates and business parks such as Newbury Retail Park included. A few photographs and the unit address let us price the work.
Is hospital work, at somewhere like Goodmayes Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long does movement joint sealing take?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Expansion joint sealing in Seven Kings, done properly
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in. We work on podiums and floor movement joints, precast concrete panel joints and car park decks and ramps, and what we’re called in for most is sealant peeling off one face of the joint and chipped joint edges on forklift routes. Searching for sealant specialists in Seven Kings? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
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.

Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Agree which areas must stay open
- Let building users know which areas are affected
- Confirm the product named in the specification

Advice
General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
How the job changes by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.
Why deal with it now?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too. Where it helps, we quote both options. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

- Expansion joints split through the centre of the bead
- Previous reseals laid over old sealant
- Rain penetration at brick or block movement joints
For estates staff at a university like University of East London, which lies south-west of Seven Kings, building and paving joints are part of the planned maintenance list.
