Construction mastic for businesses in Letham

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

How we handle construction mastic in Letham

Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. Most enquiries involve window and door perimeters that won’t pass inspection and sanitary sealant damaged by following trades, on internal decorators’ caulk, cladding and panel joints and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Letham, that means joint design, primers and backing rod as standard.

In smaller places such as Letham, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email us and we will come back to it.

When to call us in Letham

Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink and internal caulk in a moving joint is normally the first to crack. Picking a flexible sealant where there’s movement keeps snags down.

Things that usually lead to an enquiry:

  • External joints sealed in damp or cold conditions that are now failing
  • Old sealant on a refurbishment that needs stripping before new work
  • Bath and shower joints scraped during the final clean
  • Missed perimeter joints on a new elevation

For contractors refurbishing units at places like Broxden Business Park, 0.9 miles south of Letham, the mastic covers cladding panels, roller-door and window perimeters.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?
  • What site paperwork they can supply

How to choose a sealant contractor

New build and refits around Letham

In Letham, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. Our job is to seal to that specification. Being in the east of Scotland, Letham gets less rain than the west coast. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External dates keep a little give.

Hotel extensions and refits, at places such as The Lovat Hotel, 1.1 miles to the south-east of Letham, normally run between busy periods, so the sealing is squeezed into short windows. Hospital estates such as Perth Royal Infirmary, 0.9 miles to the south-east of Letham, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Letham is about 1 mile west of Perth, in Perth and Kinross. Commercial clients in Letham can call on us for mastic packages. Across Perth and Kinross, 114 places are covered, Letham among them. Dundee is covered too, some 20 miles away.

Commercial clients in Letham

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Frames fitted out of tolerance
  • Faulty frames rather than failed sealant
  • Designing joint widths or choosing the specification (that sits with the designer)

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Floor and skirting junctions
  • Window and door perimeters
  • Cladding and panel joints
  • Internal decorators’ caulk

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Letham: questions and answers

Is a smaller place like Letham outside your area?

No. Small places get the same service as large ones. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Broxden Business Park, close to Letham?

Yes. Our area takes in Letham and its surroundings, with estates and business parks such as Broxden Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Can the building stay open while you work?

In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What affects the price in Letham

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Location, for remote and island sites
  • Which sealant the job calls for

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What we need to price the job

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

  • Clear photos of the problem areas
  • The postcode of the building
  • Your programme or deadline
  • Drawings or a marked-up plan, if available

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Travel to smaller Scottish places like Letham is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. We walk the site or review drawings to understand the package.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

Before we start on site

  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Get a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
