Mastic sealing across Westmuir

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

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Frames that are rotten, warped or broken
  • Misted or failed double-glazed units
  • Materials that need asbestos testing before work

If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think before you book.

What we seal

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

How we handle mastic sealing in Westmuir

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. If you are dealing with cracked, hardened mastic round windows on a block and repeated reactive repairs to the same buildings, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Westmuir, preparation and product choice get the time they need.

Travel to smaller places like Westmuir is planned so several buildings can be done on one trip. Send addresses and photographs for a quote covering the batch.

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

Leave it or put it right?

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. For buildings near Westmuir, dealing with all the failing joints at once saves return trips. Send photos and we’ll quote for everything together.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Why appoint us

  • Fully insured
  • 12 months’ guarantee on every job
  • Clear, fixed quotes
  • One phone line for London, the South East and Scotland

Take a look at what affects the cost and how we’re accredited.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building near Westmuir, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  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. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
  • Arrange parking or a loading space
  • Confirm the product named in the specification

What affects the price in Westmuir

We price every job individually. The things that drive the figure:

  • Which sealant the job calls for
  • How much there is to seal
  • Removal of failed or old sealant
  • Joint width, depth and condition

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Send us:

  • Any dates the work must fit around
  • Any specification or named product
  • Whether an asbestos survey exists
  • What the building is and how it’s used

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Your questions answered

Will you price a mastic programme across our Westmuir portfolio?

Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we will give a fixed quote.

Does your area include sites such as Muirhead Industrial Estate, near Westmuir?

Yes. Our area takes in Westmuir and its surroundings, with estates and business parks such as Muirhead Industrial Estate included. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Do you guarantee the mastic work?

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

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can people stay in the building while you reseal?

Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.

Doing it in-house

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.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

When to call us in Westmuir

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Site and facilities staff are often the first to spot these:

  • Damp patches beside frames
  • Movement joints with sealant missing
  • Draught complaints from residents or tenants
  • Window mastic that has split and shrunk

Historic properties like Glamis Castle (3.1 miles south-east of Westmuir) show the age of some local stock, where frame mastic must suit soft brick or stone.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What level of public liability insurance do they hold?
  • What site paperwork they can supply
  • Are they CHAS accredited or on Constructionline?
