Mastic sealing across Kirdford

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

Kirdford: questions and answers

Can one quote cover a number of our buildings near Kirdford?

Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.

Is Kirdford too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Do you guarantee the mastic work?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Can you take on resealing for a block portfolio?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

What about access for upper-floor joints?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.

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.

Mastic sealing in Kirdford, done properly

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. We work on shopfronts below residential blocks, communal kitchens and washrooms and communal entrances and stairwells, and the usual reasons a site gets in touch are leaks at window and door perimeters and cracked, hardened mastic round windows on a block. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kirdford is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For owners with a single building near Kirdford, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Materials that need asbestos testing before work
  • Frames that are rotten, warped or broken
  • Water coming in from the roof or rainwater goods

Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly before you book.

Where we work in Kirdford

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

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a building around Kirdford, 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. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Before we start on site

  • Let us know about inductions and permits
  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings

Frames, entrances and external joints in Kirdford

Central London is about 38 miles from Kirdford. 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. Rainfall across the South East, Kirdford included, is lower than in many parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first.

Older community buildings, The Parish Church of St John the Baptist among them, often have frames of mixed ages whose mastic varies. Older buildings near Kirdford, from historic houses such as Petworth House, 4.1 miles to the south-west of Kirdford, to more modest stock, need compatible products when frames are resealed. Buildings close to stations like Billingshurst station (to the east of Kirdford) are often flats over shops, with frame mastic to keep sound.

Kirdford is about 10 miles west of Horsham, in West Sussex. We cover Kirdford and the rest of West Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Kirdford is one of 373 places we cover in West Sussex for mastic joints. Sites around Brighton have their own page, about 23 miles away.

Commercial sites across RH14 are covered for mastic joints. For a building on Oakside, Poplar Walk and Maple Drive or nearby, we can quote for mastic joints. Sites close to Kirdford are covered too, including Mackerel's Common (1 mile north), Balls Cross (2 miles west), Wisborough Green (2 miles east), Plaistow (2 miles north) and Ifold (2 miles north). Nearby towns on our patch include Horsham (10 miles east), Littlehampton (15 miles south), Storrington (9 miles south-east), Billingshurst (5 miles east), Bewbush (15 miles east) and Angmering (15 miles south).

Commercial clients in Kirdford

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What the job involves on each surface

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.

Window and door perimeters on blocks

Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.

How the quote is worked out

These are the things that shape the price:

  • How accessible the joints are
  • The site’s rules and procedures
  • Working within restricted access windows
  • Quantities, in metres or numbers

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area
  • The postcode of the building
  • Access details, including height

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call 01277 525 020 or email the details over.

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Log resealing dates block by block
  • Reduce knocks to communal area joints
  • List the paperwork your organisation requires when you send details
  • Share the asbestos register when you send details

If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
