Mastic sealing in Norton

Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have complaints coming in block by block and draughts at frames across a block, we can help. For commercial sealant work in Norton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Rural conversions near places like Norton often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaks from above rather than through a joint
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Failed window or door frames, which need a window contractor

If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think.

Surfaces we seal

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

Norton: questions and answers

Do you work in occupied care homes around Norton?

Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.

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

Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Do you guarantee the mastic work?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Can you seal joints high up on a block?

It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

What paperwork can you provide?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

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, and each stage is agreed with your contact.

How the job changes by surface

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent and easier to manage.

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.

Common problems we fix in Norton

Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.

These are often picked up first by site or facilities staff:

  • Draughts at frames across a block
  • Water getting in round frames after rain
  • Old repairs sealed over failed mastic
  • Estate-wide sealant that is simply worn out

If your remit includes a building such as Ormiston Six Villages Academy, frame and door mastic can be programmed for the holidays.

Comparing quotes

  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • Their pre-qualification and accreditations
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around Norton can be grouped with others nearby. A fixed quote is given before anything starts.

  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 sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

What we need from you

  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions
  • Let building users know which areas are affected

Get a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

What sets the cost

What shapes the price:

  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • Whether the work must be split into stages

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • Your programme or deadline
  • Whether the building will be occupied during the work
  • Any specification or named product
  • Access details, including height

To get a fixed quote, ring 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.

Norton is in the South East, one of the UK’s drier regions. 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.
