About our mastic sealing in Wix

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. Site teams most often ask us about damp patches beside frames and failed external movement joints, on external wall and movement joints, communal entrances and stairwells and shopfronts below residential blocks. Whoever orders the work in Wix, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For owners with a single building near Wix, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Frames, entrances and external joints in Wix

With the shore within about 3 miles, Wix counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

If you own or manage units on a site such as Oak Business Park, 2 miles to the south-east of Wix, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Historic properties like Thorpe Hall, 4.3 miles south of Wix, show the age of some local stock, where frame mastic must suit soft brick or stone. If your remit includes a building such as Wix and Wrabness Primary School, frame and door mastic can be programmed for the holidays.

Wix is about 5 miles west of Harwich, in Essex. Commercial clients in Wix use us for work on mastic joints. Wix is one of 644 places in Essex on our list. Sites around London have their own page, about 60 miles away.

Business premises anywhere in CO11 are within our area. If your site is on Hunters Court, Colchester Road and Harwich Road or close by, we can quote for mastic joints. Close to Wix, our area also takes in Wix Green (1 mile east), Bradfield (2 miles north-west), Bradfield Heath (2 miles north-west), Great Oakley (2 miles east) and Wrabness (2 miles north-east).

Leave it or put it right?

Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. One visit to deal with every failing joint makes more sense than several trips to a place like Wix, rather than one at a time. Send photographs of each area and we will quote for the lot.

A quote for mastic joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

What you get with us

  • A fixed quote before work starts
  • Workmanship guaranteed for 12 months
  • Specification-led, product-correct work
  • Sealing commercial buildings since 2005

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a building around Wix, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Before we start on site

  • Point out parking and an unloading spot
  • Agree which areas must stay open
  • Have the specification and drawings to hand

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Quoting for work in Wix

A fixed quote reflects the actual work. It allows for:

  • How accessible the joints are
  • Which sealant the job calls for
  • The total length or number of joints
  • Whether the work must be split into stages

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done
  • Whether an asbestos survey exists
  • How the joints are reached, and at what height

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email the details over if you’d rather talk the job through.

What the job involves on each surface

Window and door perimeters on blocks

On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Broken glass or failed sealed units
  • Materials that need asbestos testing before work
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

Where we work in Wix

  • Window and door perimeters on blocks
  • Communal entrances and stairwells
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Balcony and threshold joints
  • Shopfronts below residential blocks

Looking after the joints

A few simple habits keep the new joints working:

  • Include mastic in your cyclical inspections
  • Plan resealing building by building rather than complaint by complaint
  • List the paperwork your organisation requires when you send details
  • Make it easy for occupiers to report draughts

If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it.

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

Wix: questions and answers

Will you take on work at estates like Oak Business Park, close to Wix?

Yes, sites like Oak Business Park are within our area, along with the rest of Wix. A few photographs and the unit address let us price the work.

Does the sea air around Wix change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

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 in line with the dutyholder’s asbestos management.

Do you do block-wide mastic programmes?

We can. We survey and price each building, then work through them in order, and the programme can start with the worst.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
