Need mastic sealing in Roke?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

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

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Mastic sealing in Roke, done properly

Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. Most enquiries involve a mix of products and colours from past repairs and leaks at window and door perimeters, across communal kitchens and washrooms, external wall and movement joints and balcony and threshold joints. Most enquiries from Roke start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Roke, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • How accessible the joints are
  • How much there is to seal
  • Travel to remote or island sites
  • Which sealant the job calls for

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

We can often quote from photos and a few details. It helps to include:

  • The site address and postcode
  • Access details, including height
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

When to bring in a specialist

Paperwork matters too. 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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Your questions answered

Does your area include sites such as Monument Business Park, near Roke?

Yes. Estates, retail parks and business parks around Roke, Monument Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Is Roke off your patch?

Not at all. Roke is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you plan resealing across several buildings?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Is asbestos a concern with old mastic?

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.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we will price the work to it.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

What will the job cost?

We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

When to call us in Roke

Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.

Typical triggers for a call:

  • Failed external movement joints
  • Window mastic that has split and shrunk
  • Draughts at frames across a block
  • Worn sealant at communal door frames

Trustees of buildings like Church of St Helen can bring frame and external mastic into a planned maintenance list.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Their pre-qualification and accreditations
  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

Mastic sealing in Roke: the local picture

The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. Roke is about 44 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

If you own or manage units on a site such as Monument Business Park, 2.8 miles to the north-east of Roke, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Historic properties like Brightwell Manor, 3.4 miles to the south-west of Roke, show the age of some local stock, where frame mastic must suit soft brick or stone.

Roke is about 7 miles east of Didcot, in Oxfordshire. Businesses, contractors and managing agents in Roke can call on us for mastic joints, as part of our coverage of Oxfordshire. Our Oxfordshire coverage takes in 423 places, large and small. Our Oxford page has more on work in that area (10 miles or so).

Close to Roke, our area also takes in Ewelme (2 miles south-east), Brightwell Baldwin (2 miles north-east), Chalgrove (2 miles north), Britwell Salome (3 miles east) and Watlington (4 miles east).

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For a building around Roke, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we look at the mastic on each building and note what needs replacing.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

What we need from you

  • Point out any areas we must not close
  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed

Advice

Aftercare for building managers

A few simple habits keep the new joints working:

  • Avoid piecemeal callouts where you can
  • Include mastic in your cyclical inspections
  • Ask residents or tenants to report leaks and draughts early
  • Reduce knocks to communal area joints

Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
