Mastic sealing in Milton Keynes

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Mastic sealing in Milton Keynes, 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. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells, and the failures we’re asked to look at most are no planned programme for sealant and draught complaints from residents or tenants. A single leaking joint is often how a building in Milton Keynes first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In a large town like Milton Keynes, landlords and agents with a portfolio usually have mastic of similar age across many buildings. Grouping them under one programme and one quote keeps things simple.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Signs you need mastic sealing in Milton Keynes

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.

Look out for the following:

  • Patchy repairs in mismatched sealant
  • Damaged joints in communal entrances and corridors
  • Complaints coming in block by block
  • Open joints in brickwork or panels

Student accommodation around universities such as University of Bedfordshire Milton Keynes Campus (to the north-east of Milton Keynes) is normally managed block by block, which suits a planned mastic programme.

What your quote should include

  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid
  • Their pre-qualification and accreditations
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • Which sealant the job calls for
  • Access and working height
  • Location, for remote and island sites
  • Quantities, in metres or numbers

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 you’ll have a fixed figure to work with.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • What the building is and how it’s used
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply

For a fixed quote, speak to us on 01277 525 020 or email the details over, telling us the site location and the nature of the job. You can also send details through our quote form.

Blocks and managed buildings in Milton Keynes

Rainfall across the South East, Milton Keynes included, is lower than in many parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first. There are four care or nursing homes within about 2 miles of Milton Keynes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.

If your remit includes a building such as Summerfield School, frame and door mastic can be programmed for the holidays. Property owners at sites such as Central Retail Park (to the north-west of Milton Keynes) can have mastic renewed between lettings.

Maintenance after handover

A few simple habits keep the new joints working:

  • Check sealant joints during planned building inspections
  • Prioritise elevations facing the weather
  • Avoid piecemeal callouts where you can
  • Log resealing dates block by block

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.

Questions we are asked in Milton Keynes

Do you work in occupied care homes around Milton Keynes?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Can you quote for a block close to Milton Keynes Central station?

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

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. 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. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

Is Milton Keynes in your area?

Yes. Sites across Milton Keynes are covered.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.
