How we handle mastic sealing in Broughton

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. We work on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms, and what we’re called in for most is no planned programme for sealant and cracked, hardened mastic round windows on a block. Whoever orders the work in Broughton, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Older buildings and conversions around places like Broughton mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Work in places the size of Broughton is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Different surfaces, different methods

External movement joints

External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.

Mastic sealing in Broughton: the local picture

Central London is about 46 miles from Broughton. Managed blocks of flats are a big part of commuter-belt property. There are two care or nursing homes within about 2 miles of Broughton. Care home owners need frame and external mastic kept sound without unsettling residents.

Student accommodation around universities such as The Open University, 1.9 miles south of Broughton, is normally managed block by block, which suits a planned mastic programme. If you look after a block within reach of Woburn Sands station, which lies south-east of Broughton, frame and balcony mastic can be renewed on one programme.

Broughton is about 3 miles east of Milton Keynes, in Milton Keynes. Anywhere in MK10, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Broughton is one of 62 places we cover in Milton Keynes. For work in that direction, see our Oxford page, about 31 miles away.

Postcode districts covered here: MK10, MK16 and MK15. If your site is on Ripley Road, Milton Road and Aureol Lane or close by, we can quote for mastic joints. If your building is just outside Broughton, we cover Kingston (1 mile south), Moulsoe (1 mile north-east), Glebe Farm (2 miles south-east), Wavendon (2 miles south-east) and Salford (2 miles east). Nearby towns on our patch include Milton Keynes (3 miles west), Bletchley (4 miles south-west), Newport Pagnell (3 miles north-west), Bletchley and Fenny Stratford (4 miles south), Furzton (4 miles south-west) and Whitehouse (5 miles west).

When it isn’t the sealant

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

  • Water coming in from the roof or rainwater goods
  • Failed window or door frames, which need a window contractor
  • Materials that need asbestos testing before work

If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think.

Surfaces we seal

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

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Prioritise elevations facing the weather
  • Share the asbestos register when you send details
  • Mention RAMS, insurance or CSCS requirements up front
  • Make it easy for occupiers to report draughts

Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Common problems we fix in Broughton

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

These are often picked up first by site or facilities staff:

  • Open joints in brickwork or panels
  • Estate-wide sealant that is simply worn out
  • Patchy repairs in mismatched sealant
  • No planned programme for sealant

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

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • Their pre-qualification and accreditations
  • How the joint faces will be prepared and primed
  • Whether old or failed sealant will be cut out, not overlaid

Common questions from Broughton clients

Is a smaller place like Broughton outside your area?

No. Places such as Broughton are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Does your area include sites such as Wavendon Business Park, near Broughton?

Yes. We cover Broughton and the area around it, including industrial estates, business parks and retail parks such as Wavendon Business Park. Photos and a short description are enough for a first look.

Do you seal on top of existing sealant?

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

Do you supply RAMS and insurance details?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Can you plan resealing across several buildings?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

Can you seal joints high up on a block?

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