About our mastic sealing in Westcliff-on-Sea

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Westcliff-on-Sea carry our 12-month guarantee. We work on communal entrances and stairwells, balcony and threshold joints and external wall and movement joints, and the usual reasons a site gets in touch are movement joints with sealant missing and no planned programme for sealant. Whether you call it commercial sealant work, mastic application or joint sealing, in Westcliff-on-Sea it comes down to the same thing: the right product in a properly prepared joint.

In a smaller place such as Westcliff-on-Sea, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, 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. For a site in Westcliff-on-Sea, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Questions we’re asked in Westcliff-on-Sea

Is Westcliff-on-Sea too small for you to travel to?

No. Places such as Westcliff-on-Sea are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Does a coastal location like Westcliff-on-Sea affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Have the asbestos survey to hand for older buildings
  • Start inspections with the most exposed faces
  • Log resealing dates block by block
  • Avoid piecemeal callouts where you can

Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.

For owners and agents in Westcliff-on-Sea

Westcliff-on-Sea sits close to the coast, within about 1 mile. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. Westcliff-on-Sea has three care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents.

For owners of several units at places like Tickfield Industrial Estate, which lies north-east of Westcliff-on-Sea, one programme can deal with frame and external mastic across the lot. Older community buildings, St Saviour's among them, often have frames of mixed ages whose mastic varies. Student accommodation around universities such as University of Essex (to the east of Westcliff-on-Sea) is typically managed block by block, which suits a planned mastic programme.

What sets the cost

The price varies from site to site. It mainly depends on:

  • The total length or number of joints
  • Travel to remote or island sites
  • Which sealant the job calls for
  • Access and working height

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • A wide shot and a close-up of the area
  • The site address and postcode
  • Drawings or a marked-up plan, if available
  • When you need the work done

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Water coming in from the roof or rainwater goods
  • Leaks through the frame itself rather than the perimeter
  • Asbestos-containing sealant, which we don’t remove

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think before you book.

Surfaces we seal

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

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

How the job changes by surface

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.

Commercial and mixed-use buildings

Where retail and residential share a building, so phasing has to suit both. We plan around the site hours and access windows you give us.
