Mastic sealing for businesses in Slindon Common

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Mastic sealing in Slindon Common, done properly

Across Slindon Common and the rest of West Sussex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are mastic failing across several blocks on an estate and a mix of products and colours from past repairs. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Slindon Common it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Owners and agents with buildings around smaller places such as Slindon Common tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

Every job we finish is backed by a 12-month workmanship guarantee, in Slindon Common as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Slindon Common

A fixed quote reflects the actual work. It takes account of:

  • How much there is to seal
  • Any access equipment needed
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first

Pricing mastic joints depends on how many there are, their condition and the access. Call for a quote.

Sending details for a quote

However big the job, these details speed things up:

  • When you need the work done
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call 01277 525 020 or email us.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Materials that need asbestos testing before work
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Broken glass or failed sealed units

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Surfaces we seal

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

Questions about Slindon Common

Is Slindon Common off your patch?

Not at all. Slindon Common is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work for managing agents with blocks near Barnham station?

Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

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.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Can you plan resealing across several buildings?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Slindon Common need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Getting the site ready

External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.

Keeping the joints sound

For the best life from the joints:

  • Reduce knocks to communal area joints
  • List the paperwork your organisation requires when you send details
  • Encourage occupiers to report problems at frames
  • Have the asbestos survey to hand for older buildings

Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.

Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.

What we’re called out for in Slindon Common

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Any of the following is a good reason to get the joints checked over:

  • Water getting in round frames after rain
  • Patchy repairs in mismatched sealant
  • Repeated reactive repairs to the same buildings
  • Damaged joints in communal entrances and corridors

With historic buildings such as Bignor Roman Villa (to the north of Slindon Common) in the wider area, owners of older properties around Slindon Common should expect mastic to need a product that suits old masonry.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
  • The named product and why it was chosen
  • How joint depth will be controlled
