Mastic sealing across Ardingly

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Why deal with it now?

Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. One visit to deal with every failing joint makes more sense than several trips to a place like Ardingly, rather than one at a time. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Why clients in Ardingly choose us

  • Sealing commercial buildings since 2005
  • Work to your specification and the manufacturer’s guidance
  • Failed material removed, not covered up
  • Colour agreed before work starts

Mastic sealing in Ardingly, done properly

Across Ardingly 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, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. The enquiries we see most involve movement joints with sealant missing and a mix of products and colours from past repairs, across communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints. For commercial sealant work in Ardingly, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For buildings around smaller places like Ardingly, we group work so one trip covers it. Photos of each elevation help us quote accurately.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Asbestos-containing sealant, which we don’t remove
  • Substrate edges that need repairing first

If you are not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Surfaces we seal

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

Different surfaces, different methods

Tenement and older buildings

Stone needs a neutral-cure product, so we pick a grade that won’t mark it.

External movement joints

External movement joints take up expansion and contraction. Once that sealant goes, rain can reach the wall.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, 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 work around Ardingly, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • Agree which areas must stay open

Ask for a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or use the quote form.

For owners and agents in Ardingly

Ardingly lies roughly 31 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Churches, halls and community buildings such as St Peter's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For a school such as St Peter's CofE Primary School, perimeter mastic on windows and doors is a holiday job. Property owners at sites such as Horsted Keynes Business Park (2 miles east of Ardingly) can have mastic renewed between lettings.

Ardingly is about 3 miles north of Haywards Heath, in West Sussex. If you’re looking for mastic sealing in Ardingly, we can help. 373 places across West Sussex fall within our area, Ardingly among them. There’s a separate page for Brighton, about 15 miles away.

Questions about Ardingly

Can you quote for a block close to Balcombe station?

Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

Does your area include sites such as Horsted Keynes Business Park, near Ardingly?

Yes, sites like Horsted Keynes Business Park are within our area, along with the rest of Ardingly. Send details of the unit and the work through our quote form for a quick quote.

What paperwork can you provide?

Let us know your requirements: 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.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.

What affects the price in Ardingly

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Backing rod, priming and other preparation
  • Removal of failed or old sealant
  • The product specified
  • Phasing around occupants

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Before you send an enquiry

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

  • A wide shot and a close-up of the area
  • The site address and postcode
  • Anything awkward about access or site hours
  • The product your specification calls for

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Building owners, agents and FMs in Ardingly

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Ardingly can form part of a wider programme across West Sussex.
