About our construction mastic in Frating

The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you have early adhesion failures on new external joints and oversized or tapered gaps around new frames, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Frating is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Frating bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Distance, for remote addresses
  • How accessible the joints are
  • Whether the work must be split into stages
  • The site’s rules and procedures

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • The postcode of the building
  • Any specification or named product
  • The asbestos register, for older buildings
  • Your programme or deadline

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

How the job changes by surface

Window and door perimeters

A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting.

Kitchens and utility areas

Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product, food-safe where food contact is possible.

When it isn’t the sealant

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

  • Joints damaged after sign-off by following trades
  • Joint design decisions that belong to the architect or engineer
  • Defective windows, doors or glazing units (the supplier or installer’s job)

If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Surfaces we seal

  • Floor and skirting junctions
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Window and door perimeters

Common problems we fix in Frating

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Choosing the right product for each joint reduces that.

What tends to prompt an enquiry:

  • Different trades sealing to different standards
  • Cracks opening in caulked internal joints
  • Frame perimeters left unsealed or poorly sealed
  • Sealant knocked or painted over by other trades

New units and refits on sites such as Plough Road Business Centre (to the east of Frating) need their panel and perimeter joints sealed to the specification.

What to look for in a quote

  • Proof of insurance
  • Who will actually carry out the work
  • How they’ll work around occupants
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Frating are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Plots or floors are sealed as they’re handed over.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

What we need from you

  • Warn occupants and staff about the work
  • Agree which areas must stay open
  • Have the specification and drawings to hand

Advice

Work for main contractors and building owners

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Mastic packages on Frating sites

Frating sits close to the coast, within about 3 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Rainfall across the South East, Frating included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

University estates such as University of Essex, 3.5 miles to the west of Frating, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Extensions at sites like Essex County Hospital, 6 miles west of Frating, usually sit beside working departments, and the mastic follows strict access rules.

Frating is about 3 miles east of Wivenhoe, in Essex. Frating sits inside our coverage and the rest of Essex, with the same fixed quotes and 12-month guarantee as everywhere else. Our Essex coverage takes in 644 places, large and small. Our London page has more on work in that area (54 miles or so).

Postcode districts covered here: CO7. Streets here include Church Road and Rectory Road, and sites on any of them can send details for a fixed quote. If your building is just outside Frating, we cover Frating Green (1 mile north-east), Balls Green (1 mile north-east), Thorrington (1 mile south-east), Hare Green (2 miles north-east) and Great Bentley (2 miles east). Nearby towns on our patch include Colchester (6 miles west), Clacton-on-Sea (7 miles south-east), Harwich (11 miles north-east), Camulodunum (7 miles west), Greenstead (4 miles north-west) and Tiptree (12 miles west).

Common questions from Frating clients

Will you plan work around the academic year at somewhere like University of Essex?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like Frating outside your area?

No. Places such as Frating are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Is colour matching possible?

That depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Can fire-rated sealing at service penetrations be included?

Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. Fire-stopping design and sign-off sit with the designer and building control.
