Mastic sealing across Lambs Green

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Mastic sealing in Lambs Green

Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. Most enquiries involve water getting in round frames after rain and movement joints with sealant missing, on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints. Facilities teams, main contractors and managing agents in Lambs Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Lambs Green, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

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.

Mastic sealing around Lambs Green: what changes locally

Rainfall across the South East, Lambs Green included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Lambs Green is about 27 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.

If you look after a block within reach of Faygate station (1.4 miles south of Lambs Green), frame and balcony mastic can be renewed on one programme. For owners of several units at places like Holmbush Potteries Industrial Estate, 1.7 miles to the south-east of Lambs Green, one programme can deal with frame and external mastic across the lot.

Lambs Green is about 3 miles west of Crawley, in West Sussex. If you’re looking for mastic sealing in Lambs Green, we can help. Our West Sussex coverage takes in 373 places, from busy centres to rural villages. We also cover Brighton, some 20 miles away.

We cover the RH12 postcode districts for mastic joints. Just outside Lambs Green, we also work in Rusper (1 mile west), Ifieldwood (1 mile north-east), Bewbush (2 miles south-east), Ifield (2 miles east) and Russ Hill (2 miles north). Further afield, our area takes in Crawley (3 miles east), Horsham (4 miles south-west), Haywards Heath (11 miles south-east), Burgess Hill (12 miles south-east), East Grinstead (11 miles east) and Broadfield (3 miles south-east).

Around Lambs Green

We work on buildings around Ifield Community College, among other places. The nearest railway station is Faygate station, roughly 1.4 miles south of the centre. A little further out are Crawley Museum (3.1 miles east) and Crawley Hospital (2.7 miles east). For a walk, there’s Warnham LNR and Tilgate Lake.

When to call us in Lambs Green

UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.

Site and facilities staff are often the first to spot these:

  • Draughts at frames across a block
  • Worn sealant at communal door frames
  • Estate-wide sealant that is simply worn out
  • Open joints in brickwork or panels

If your remit includes a building such as Rusper Primary School, frame and door mastic can be programmed for the holidays.

Questions to ask before you appoint anyone

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Questions about Lambs Green

Is a smaller place like Lambs Green outside your area?

Not at all. Lambs Green is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

We manage a building near Faygate station. Can you help?

Yes, and several blocks can go on one quote. We work to your notice and access arrangements.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can you send RAMS and CSCS details before starting?

Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you do block-wide mastic programmes?

We can. We survey and price each building, then work through them in order, and the programme can start with the worst.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

What affects the price in Lambs Green

To price the job, we consider:

  • Working within restricted access windows
  • The product specified
  • How much there is to seal
  • Distance, for remote addresses

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

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

  • Whether the building will be occupied during the work
  • The postcode of the building
  • Any specification or named product
  • Clear photos of the problem areas

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or use the quote form.

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Protect low-level joints in entrances
  • Make it easy for occupiers to report draughts
  • Start inspections with the most exposed faces
  • Share the asbestos register when you send details

Keep records of when each building was resealed. It helps plan the next round and shows what was done.

One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For work around Lambs Green, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we’ll be in
  • Confirm the product named in the specification

Request a quote

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call 01277 525 020 or email a schedule or drawings to discuss it first.

Why it’s worth doing now in Lambs Green

Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Converted and older buildings near places like Lambs Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
