Mastic sealing across Holland-on-Sea

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Mastic sealing in Holland-on-Sea, done properly

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Holland-on-Sea carry our 12-month guarantee. We work on balcony and threshold joints, window and door perimeters on blocks and communal kitchens and washrooms, and the failures we’re asked to look at most are patchy repairs in mismatched sealant and window mastic that has split and shrunk. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Holland-on-Sea, that means joint design, primers and backing rod as standard.

For landlords and associations with stock in and around Holland-on-Sea, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common problems we fix in Holland-on-Sea

Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.

Any of the following is a good reason to get the joints checked over:

  • Worn sealant at communal door frames
  • Repeated reactive repairs to the same buildings
  • Water getting in round frames after rain
  • Window mastic that has split and shrunk

With historic buildings such as Thorpe Hall (3.4 miles north of Holland-on-Sea) in the wider area, owners of older properties around Holland-on-Sea should expect mastic to need a product that suits old masonry.

What your quote should include

  • Whether primer will be used where the manufacturer specifies it
  • Their approach to joint depth and backing
  • Whether old or failed sealant will be cut out, not overlaid
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

Why act early in Holland-on-Sea

Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. For buildings in places like Holland-on-Sea, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why clients in Holland-on-Sea choose us

  • A fixed quote before work starts
  • Joints cleaned back to sound surfaces
  • RAL and finish matching where the product range allows
  • Work to your specification and the manufacturer’s guidance

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites around Holland-on-Sea. Several sites can go on one quote, so there’s one set of paperwork to deal with.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. For a site in Holland-on-Sea, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  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.

What we need from you

  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Common questions from Holland-on-Sea clients

Does your area include sites such as Telford Business Park, near Holland-on-Sea?

Yes. Our area takes in Holland-on-Sea and its surroundings, with estates and business parks such as Telford Business Park included. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Will you take on a block within reach of Clacton-On-Sea station?

Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Can you follow the specification on our project?

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

What if the old mastic contains asbestos?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Do you work in Holland-on-Sea?

Yes. We take on work across Holland-on-Sea, with one number for every area we cover.

Frames, entrances and external joints in Holland-on-Sea

Holland-on-Sea is within about 1 mile of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. The South East is one of the drier parts of the UK. 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.

Landlords with units on estates such as Telford Business Park (to the north-west of Holland-on-Sea) can bring frame, door and external mastic across several units into one programme. Trustees of buildings like St Bartholomews Church Hall can bring frame and external mastic into a planned maintenance list.

Holland-on-Sea is about 2 miles east of Clacton-on-Sea, in Essex. Commercial clients in Holland-on-Sea can call on us for mastic joints. Holland-on-Sea is one of 644 places in Essex on our list for mastic joints. London is covered too, some 59 miles away.

Commercial sites across CO15 are covered. We cover commercial and managed buildings on York Road, Cliff Road and Nansen Road. If your building is just outside Holland-on-Sea, we cover Clacton-on-Sea (2 miles west), Bocking's Elm (3 miles west), Pig Street (3 miles north-west), Little Clacton (3 miles north-west) and Thorpe Cross (3 miles north). Bigger towns within reach include Colchester (14 miles north-west), Harwich (9 miles north), Camulodunum (15 miles west), Greenstead (13 miles north-west), Wivenhoe (11 miles west) and Brightlingsea (7 miles west).

Looking after the joints

To get the most from the new sealant:

  • Make mastic part of routine maintenance checks
  • Check the asbestos register before any old mastic is disturbed
  • Ask residents or tenants to report leaks and draughts early
  • Mention RAMS, insurance or CSCS requirements up front

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.

Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
