Mastic sealing for commercial buildings in Broomershill

Across Broomershill 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. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. Site teams most often ask us about water getting in round frames after rain and complaints coming in block by block, on communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks. Whoever orders the work in Broomershill, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Broomershill, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What the job involves on each surface

Window and door perimeters on blocks

Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. We’ll confirm the colours available for the specified product.

External movement joints

Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Substrate edges that need repairing first
  • Materials that need asbestos testing before work
  • Misted or failed double-glazed units

If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think.

Surfaces we seal

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

For owners and agents in Broomershill

Rainfall across the South East, Broomershill included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Broomershill is about 41 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.

If you look after a block within reach of Pulborough station, 1.3 miles south-west of Broomershill, frame and balcony mastic can be renewed on one programme. Landlords with units on estates such as Broomers Hill Business Park, 0.6 miles to the north of Broomershill, can bring frame, door and external mastic across several units into one programme.

Broomershill is about 10 miles south-west of Horsham, in West Sussex. Anywhere in RH20, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

What we’re called out for in Broomershill

Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Cleaning products add to the wear.

Most enquiries start with something like this:

  • Complaints coming in block by block
  • Patchy repairs in mismatched sealant
  • Leaks at window and door perimeters
  • Occupiers reporting cold air round windows

Older buildings near Broomershill, from historic houses such as Old Place Manor, 1 mile west of Broomershill, to more modest stock, need compatible products when frames are resealed.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with

Questions to ask before you appoint anyone

Looking after the joints

Once the work is signed off, these steps help:

  • Check sealant joints during planned building inspections
  • Mention RAMS, insurance or CSCS requirements up front
  • Have the asbestos survey to hand for older buildings
  • Plan resealing building by building rather than complaint by complaint

Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Cost factors for mastic joints

We price every job individually. The main factors are:

  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits
  • Phasing around occupants

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

To price the job accurately, we need to understand the site. Useful things to include:

  • When you need the work done
  • A wide shot and a close-up of the area
  • Approximate linear metres or a joint schedule
  • Specification clauses that apply

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or send photos by email.

Common questions from Broomershill clients

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

Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Does your area include sites such as Broomers Hill Business Park, near Broomershill?

Yes. Our area takes in Broomershill and its surroundings, with estates and business parks such as Broomers Hill Business Park included. A few photos and the unit address let us price the work.

What about access for upper-floor joints?

Every block is different. We agree access with you at quote stage so there are no surprises.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Can you reseal a whole block or estate?

Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

Do you seal on top of existing sealant?

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

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Broomershill, 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 we look at the mastic on each building and note what needs replacing.
  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. Completed joints are inspected and carry a 12-month workmanship guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Point out parking and an unloading spot
  • Move anything stored against the joints
