When to call us in Old Town

The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

Common reasons buildings call us in:

  • Complaints coming in block by block
  • The same joint failures repeated across a portfolio
  • Worn sealant at communal door frames
  • Draughts at frames across a block

Student accommodation around universities such as University of Brighton Eastbourne Campus (to the south of Old Town) is usually managed block by block, which suits a planned mastic programme.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Is the sealant right for the movement and the substrate?
  • What site paperwork they can supply
  • How they’ll work around occupants

About our mastic sealing in Old Town

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on balcony and threshold joints, window and door perimeters on blocks and communal kitchens and washrooms, and the failures we are asked to look at most are the same joint failures repeated across a portfolio and damaged joints in communal entrances and corridors. One point of contact handles commercial sealant work in Old Town from the first photos to the final walk-round, whether it’s one building or several.

Older buildings and conversions around places like Old Town mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.

Work we carry out in East Sussex comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email the details over and we’ll arrange a return visit.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a job in Old Town, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

What we need from you

  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings

Blocks and managed buildings in Old Town

Old Town is within about 2 miles of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. Old Town has two care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents.

Trustees of buildings like Church of St Mary can bring frame and external mastic into a planned maintenance list. If you own or manage units on a site such as Courtlands Road Industrial Estate, 1.1 miles to the east of Old Town, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Old Town is about 1 mile south-west of Eastbourne, in East Sussex. Our applicators travel to Old Town for work on mastic joints. We work across 308 places in East Sussex, large and small. We also cover Brighton, around 18 miles from Old Town.

Work on mastic joints is covered throughout BN21, BN20 and BN22, whatever the building. For a building on Love Lane, Mill Road and Greys Road or nearby, send details and we’ll quote for mastic joints. Close to Old Town, our area also takes in Upperton (1 mile east), Meads (1 mile south), Eastbourne (1 mile north-east), Holywell (1 mile south) and Ratton Village (1 mile north).

After the work

Keep the joints in good shape with a few simple steps:

  • Log resealing dates block by block
  • Make mastic part of routine maintenance checks
  • Look at the sunniest and most exposed elevations first
  • Encourage occupiers to report problems at frames

Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

One failed perimeter normally 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.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

How the job changes by surface

External movement joints

Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Your questions answered

Can you quote for a block close to Eastbourne station?

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

Does your area include sites such as Courtlands Road Industrial Estate, near Old Town?

Yes. We cover Old Town and the area around it, including industrial estates, business parks and retail parks such as Courtlands Road Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do you work in Old Town?

Yes. Old Town falls within our area, and you can speak to us on 01277 525 020 or email the details over to get started.

Can people stay in the building while you reseal?

We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.

How long will the new sealant last?

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 take on resealing for a block portfolio?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

Should maintenance staff do it?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
