How we handle mastic sealing in Elmstead

Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you have damaged joints in communal entrances and corridors and brittle perimeter mastic across a building, we can put it right, on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms alike. Facilities teams, main contractors and managing agents in Elmstead tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Elmstead, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Start inspections with the most exposed faces
  • Group repairs into a planned programme
  • Ask residents or tenants to report leaks and draughts early
  • Mention RAMS, insurance or CSCS requirements up front

Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.

Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

What sealant work can’t fix

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

  • Masonry that has broken away beside the joint
  • Glazing that needs replacing
  • Failed window or door frames, which need a window contractor

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Joints and surfaces we work on

  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • Communal kitchens and washrooms
  • External wall and movement joints

Common questions from Elmstead clients

Will you take on a block within reach of Wivenhoe station?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Is a smaller place like Elmstead outside your area?

No. Places such as Elmstead are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can people stay in the building while you reseal?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

How many days will you need on site?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

For owners and agents in Elmstead

Elmstead sits close to the coast, within about 3 miles. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Elmstead sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.

For owners of several units at places like Wivenhoe Business Centre, which lies south-west of Elmstead, one programme can deal with frame and external mastic across the lot. Owners of student blocks near University of Essex (to the west of Elmstead) can schedule frame and external mastic for the summer vacation. Buildings close to stations like Wivenhoe station (1.4 miles south-west of Elmstead) are often flats over shops, with frame mastic to keep sound.

Elmstead is about 1 mile north-east of Wivenhoe, in Essex. Our applicators travel to Elmstead for work on mastic joints, handled exactly as we handle every other area. Elmstead is one of 644 places we cover in Essex. We also cover London, around 53 miles from Elmstead.

Our process

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Elmstead, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Tell staff and tenants when we’ll be in

Why act early in Elmstead

Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Older rural buildings around Elmstead move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you’re ready.
