About our commercial sealant contractors in Redbridge

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Redbridge, the quickest start is to speak to us on 01277 525 020 or email the details over with a list of addresses. Site teams most often ask us about water staining near frames, panels or ceilings and messy, uneven beads from earlier work that let the building down, on floor and threshold joints, kitchen worktops and splashbacks and external facade joints. Looking for mastic applicators who cover Redbridge? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

In an occupied building in Redbridge, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.

For managing agents and FMs looking after premises in Redbridge, access is normally the first question: booked loading, goods-lift times, the permit system and a place to stage materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Leave it or put it right?

Putting off a reseal typically moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, which brings decorators and flooring contractors into the repair. Dealing with it while the damage stops at the bead is the cheaper route. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

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 quote and we will explain how it’s made up.

Why us?

  • Fully insured
  • Failed material removed, not covered up
  • CSCS-carded applicators
  • Colours chosen to suit frames, cladding or finishes where possible

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Suspect materials that need testing and specialist removal
  • A failed roof covering or waterproofing membrane
  • Leaks from pipework, wastes or valves (that’s plumbing)

If you’re not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Redbridge can sit alongside others in a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

What the job involves on each surface

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photos or a site visit tell us what’s needed, with colours confirmed for the product chosen.

Commercial sealant contractors in Redbridge: the local picture

There are a good number of hotels within about 2 miles of Redbridge. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet; work is planned so the hotel keeps trading. Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We plan around them and agree phasing so tenants and customers aren’t disrupted.

Access in Redbridge needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. Offices and shops close to stations such as Ilford station, 1.4 miles to the south-east of Redbridge, tend to be busy all day, so sealant work is planned around opening hours. In hotels such as Park Hotel, which lies south-east of Redbridge, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Redbridge is about 2 miles north-east of Forest Gate, in Greater London. We cover commercial sites throughout Redbridge, for single jobs and planned programmes alike. Our Greater London coverage takes in 764 places, from busy centres to rural villages. Sites around London have their own page, roughly 8 miles from Redbridge.

We cover the IG4, IG1 and IG2 postcode districts for sealant joints. For a building on Fowey Avenue, Beehive Lane and Wycombe Road or nearby, send details and we will quote for sealant joints. Just outside Redbridge, we also work in Gants Hill (1 mile east), Cranbrook (1 mile south-east), Wanstead (1 mile west), Aldersbrook (1 mile south-west) and Newbury Park (1 mile east). A short drive away, we cover London (8 miles south-west), City of Westminster (10 miles south-west), Marylebone (9 miles south-west), Kensington (12 miles south-west), St Pancras (8 miles south-west) and Shoreditch (7 miles south-west).

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Planning a London job such as one in Redbridge starts with access. Send the building rules and access times with your enquiry.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open

Questions about Redbridge

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for

Is Woodford Trading Estate, near Redbridge, within your area?

Yes. Estates, retail parks and business parks around Redbridge, Woodford Trading Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Can you supply RAMS and insurance details?

We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.

Do you work for facilities managers and managing agents?

Yes. You send the details, we return a fixed quote, and the job is done and signed off.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Could the old sealant in an older building contain asbestos?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
