How we handle mastic sealing in Shortgate

For blocks and buildings in Shortgate and across East Sussex, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on communal entrances and stairwells, window and door perimeters on blocks and communal kitchens and washrooms, and the failures we’re asked to look at most are water getting in round frames after rain and occupiers reporting cold air round windows. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Shortgate is the same: the right product in a properly prepared joint.

In and around smaller places like Shortgate, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Shortgate: questions and answers

Is a smaller place like Shortgate outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you quote for a block close to Uckfield station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

What about access for upper-floor joints?

It depends on the building. We agree access with you at quote stage so there are no surprises.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can you follow the specification on our project?

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

Can you reseal a whole block or estate?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Which sealant the job calls for
  • The site’s rules and procedures
  • Any access equipment needed
  • Joint width, depth and condition

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Details that help us quote

To price the job accurately, we need to understand the site. Send us:

  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back
  • The product your specification calls for

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email the details over.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For work around Shortgate, we aim to finish in one visit, so we ask for photos 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. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

What we need from you

  • Arrange parking or a loading space
  • Make sure the joints can be reached
  • Tell staff and tenants when we’ll be in

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Planned mastic for Shortgate portfolios

Shortgate sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 41 miles from Shortgate. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

If you own or manage units on a site such as Stone Cross Business Centre (2 miles south-east of Shortgate), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Blocks of flats and mixed-use buildings often cluster around stations such as Uckfield station (3.9 miles north of Shortgate) and their window and balcony mastic tends to age at the same rate across a building.

Shortgate is about 4 miles south of Uckfield, in East Sussex. Looking for mastic sealing in Shortgate? We can help. Our East Sussex coverage takes in 308 places, from busy centres to rural villages. Sites around Brighton have their own page, about 12 miles away.

We take on mastic joints across the BN8 postcode area, whatever the building. Nearby places we also cover include Halland (1 mile north-east), East Hoathly (2 miles east), Whitesmith (2 miles east), Chiddingly (3 miles east) and Framfield (4 miles north) for mastic joints. Further afield, our area takes in Eastbourne (12 miles south-east), Seaford (10 miles south), Lewes (6 miles south-west), Hailsham (7 miles south-east), Crowborough (10 miles north) and Newhaven (9 miles south).

Local landmarks in Shortgate

For rail, the closest station is Uckfield station, roughly 3.9 miles north. Well-known places in the area include Uckfield Community Hospital (3.6 miles north) and Tickerage Castle (4.1 miles north). Not far away are Cliffe Hill and Malling Down.

Work for main contractors and building owners

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.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Do you need mastic sealing in Shortgate?

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.

It’s worth sending us details if you spot any of the following:

  • Old repairs sealed over failed mastic
  • Repeated reactive repairs to the same buildings
  • Occupiers reporting cold air round windows
  • Damaged joints in communal entrances and corridors

Older buildings near Shortgate, from historic houses such as Glyndebourne (3.5 miles south-west of Shortgate) to more modest stock, need compatible products when frames are resealed.

What your quote should include

  • The named product and why it was chosen
  • Can the work be phased to keep areas open?
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

Why deal with it now?

Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. One visit to deal with every failing joint makes more sense than several trips to a place like Shortgate, rather than one at a time. Send photos of each area and we will quote for the lot.

Pricing mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Why clients in Shortgate choose us

  • One number for every site we cover
  • CHAS accredited contractor
  • Over 20 years of commercial sealing
  • Coloured sealants to suit the setting, where available

When to bring in a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
