Expansion joint sealing for Galleywood sites

How we handle expansion joint sealing in Galleywood

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on blockwork control joints, car park decks and ramps and brickwork movement joints, and what we are called in for most is car park joints leaking onto vehicles below and previous reseals laid over old sealant. Looking for mastic applicators who cover Galleywood? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Around Galleywood, most floor and movement joint jobs are single buildings or yards, so we gather photographs and measurements first. Getting widths, depths and traffic details up front means one visit, not two.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Questions about Galleywood

Is a hospital such as Phoenix Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Does your area include sites such as Beehive Business Centre, near Galleywood?

Yes. Our area takes in Galleywood and its surroundings, with estates and business parks such as Beehive Business Centre included. Photos and a short description are enough for a first look.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.

Is movement joint sealing guaranteed?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

How long does movement joint sealing take?

Allow a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Timings are set out in the quote along with the phasing plan.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

On site: what to expect

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Galleywood, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Send any specification or drawings in advance
  • Send your site hours and access windows
  • Make sure the joints can be reached

What the job involves on each surface

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

Leave it or put it right?

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. For buildings in places like Galleywood, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

A quote for movement joints depends on quantities, condition and access. Ask us for a fixed quote.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Movement on a scale no sealant is meant to absorb
  • Changing the joint layout or spacing of a structure
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Traffic, movement and joints around Galleywood

At least three named trading, business or retail sites lie within about 3 miles of Galleywood. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Rainfall across the South East, Galleywood included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

Phasing is what makes joint work possible on busy sites such as Clock Tower Industrial Park (1.8 miles north-west of Galleywood): one bay, aisle or car park row at a time. Hospitals like Phoenix Hospital (to the east of Galleywood) have multi-storey or surface car parks whose joints carry vehicles round the clock. Schools like St Michael's Church of England Voluntary Aided Junior School often have long brick elevations with movement joints that age quietly.

Galleywood is about 3 miles south of Chelmsford, in Essex. Anywhere in CM2, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 644 places in Essex, from busy centres to rural villages. We also cover London, some 28 miles away.
