Mastic sealing in Wivenhoe, done properly

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. If you are dealing with worn sealant at communal door frames and open joints in brickwork or panels, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Wivenhoe, preparation and product choice get the time they need.

Older buildings and conversions around places like Wivenhoe mix old masonry with newer frames. The mastic there needs to suit both surfaces.

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.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Log resealing dates block by block
  • Reduce knocks to communal area joints
  • Check the asbestos register before any old mastic is disturbed
  • Plan resealing building by building rather than complaint by complaint

Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.

The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.

Looking after buildings in and around Wivenhoe

Wivenhoe sits close to the coast, within about 2 miles. On buildings near the shore, the side facing the weather usually needs its mastic renewed first. Rainfall across the South East, Wivenhoe included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Site managers at schools like Millfields Primary School can fit frame mastic into the summer works. Owners of student blocks near University of Essex, 1.3 miles north-west of Wivenhoe, can schedule frame and external mastic for the summer vacation. Churches, halls and community buildings such as The Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Wivenhoe is about 3 miles south-east of Colchester, in Essex. Our applicators travel to Wivenhoe for work on mastic joints, handled exactly as we handle every other area. We work across 644 places in Essex. London is covered too, around 52 miles from Wivenhoe.

Commercial sites across CO7 are covered. Buildings on High Street, Station Road and Ernest Road are within our area. You will find Wivenhoe on or near the B1028, so getting applicators and materials to site is simple. We also cover Wivenhoe Quay (1 mile south), Wivenhoe Cross (1 mile north), Rowhedge (1 mile south-west), East Donyland (1 mile south-west) and Elmstead (1 mile north-east). Bigger towns within reach include Colchester (3 miles north-west), Clacton-on-Sea (9 miles south-east), Maldon (15 miles south-west), Witham (15 miles west), Harwich (14 miles east) and Camulodunum (4 miles west).

Your questions answered

Can being near the sea in Wivenhoe affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Will you take on a block within reach of Wivenhoe station?

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

Can you take on resealing for a block portfolio?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

Do you cover Wivenhoe?

Yes. We cover Wivenhoe. For a quote, give us a call on 01277 525 020 or email the details over.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Can you plan resealing across several buildings?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Why deal with it now?

Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Small buildings around Wivenhoe suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • Joints cleaned back to sound surfaces
  • Coloured sealants to suit the setting, where available
  • Colours confirmed for the specified product
  • Clear, fixed quotes

Take a look at what affects the cost and our accreditations and insurance.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Misted or failed double-glazed units
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly.

What affects the price in Wivenhoe

  • Joint width, depth and condition
  • Any access equipment needed
  • How much there is to seal
  • The product specified

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Access details, including height

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking one or more days per building, depending on the joint lengths and the access. For a job in Wivenhoe, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.

  1. A building-by-building inspection lists the failed joints.
  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. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

What we need from you

  • Agree which areas must stay open
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification
