Mastic sealing across Canewdon

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

Mastic sealing in Canewdon, done properly

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are damp patches beside frames and communal area joints that look neglected. Facilities teams, main contractors and managing agents in Canewdon tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions near places like Canewdon often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Canewdon: questions and answers

Do you cover business parks and estates near Canewdon, such as Purdey's industrial estate?

Yes. Estates, retail parks and business parks around Canewdon, Purdey's industrial estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is Canewdon too far out for you?

No. Places such as Canewdon are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you reseal a whole block or estate?

Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How do you reach windows on upper floors?

We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.

Do you work for managing agents and housing associations?

Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.

What the job involves on each surface

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and spreads the work.

Tenement and older buildings

Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.

What sets the cost

Before we quote, we look at:

  • Access and working height
  • Working within restricted access windows
  • Quantities, in metres or numbers
  • Removal of failed or old sealant

Every site prices differently: 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

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

  • What the building is and how it’s used
  • A wide shot and a close-up of the area
  • The postcode of the building
  • When you need the work done

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email us to discuss it first.

Looking after buildings in and around Canewdon

Canewdon lies roughly 37 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Canewdon is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

If you’re responsible for a building such as Church of St Nicholas, frame and door mastic needs the same attention as any other property. Blocks of flats and mixed-use buildings often cluster around stations such as Althorne station (to the north of Canewdon) and their window and balcony mastic tends to age at the same rate across a building.

Canewdon is about 3 miles north-east of Rochford, in Essex. Anywhere in SS4, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 644 places in Essex, from busy centres to rural villages. London is covered too, around 37 miles from Canewdon.

Advice

General trades versus a specialist

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.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we’re called out for in Canewdon

UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

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

  • Estate-wide sealant that is simply worn out
  • Patchy repairs in mismatched sealant
  • Repeated reactive repairs to the same buildings
  • Damaged joints in communal entrances and corridors

If your remit includes a building such as King Edmund School, frame and door mastic can be programmed for the holidays.

Comparing quotes

  • How the existing material will be dealt with
  • Their plan for phasing and protecting the area
  • Which product they’ll use, and why it suits the joint
  • What level of public liability insurance do they hold?
