About our commercial sealant contractors in Letham
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that normally surfaces as a leak, a stain or a complaint from occupiers. We are commercial sealant applicators for FMs, managing agents, landlords and contractors looking after property in Letham. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. We work on movement joints in walls and floors, floor and threshold joints and external facade joints, and the failures we’re asked to look at most are greasy, split joints in a kitchen or tea point and water staining near frames, panels or ceilings. Searching for sealant specialists in Letham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
If you look after more than one building near Letham, the work can be planned as one programme, with one quote format and one point of contact.
Scottish weather decides a lot about outside work in a place like Letham: outside joints need dry, frost-clear surfaces, so we agree a window with some give in it. Internal joints can be done whatever the day brings.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Commercial clients in Letham
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
What we’re called out for in Letham
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.
Common reasons buildings call us in:
- Hardened, chalky sealant on south-facing or exposed elevations
- Frame mastic that has hardened and come away from the wall
- Mouldy silicone around WCs, urinals and vanity tops
- Damp patches where an external joint has failed
Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- How they’ll work around occupants
- Their pre-qualification and accreditations
- How joint depth will be controlled
What Letham’s businesses ask us to seal
The east of Scotland, where Letham is, gets less rain than the west. Frost and condensation on winter mornings can still hold up external sealing. In winter, outside joints are timed for when surfaces are dry and within the product’s range
A lasting commercial joint around Letham begins with the old bead fully out and the faces clean and dry.

General trades versus a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Structural cracks or movement the joints weren’t designed for
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Faulty windows rather than failed perimeter sealant
If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.
Joints and surfaces we work on
- Window and door perimeters
- External facade joints

Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Letham, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Make sure the joints can be reached
- Tell staff and tenants when we’ll be in
Ask for a quote
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.
Advice
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Keep barriers up until the new sealant has cured
- Check joints after other trades have worked nearby
- Note dates and locations of sealant work for future planning
- Make sure contractors see the asbestos survey before cutting out old mastic
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early. If anything looks wrong, phone 01277 525 020 or use the quote form with a photo.
Sealant rarely fails all at once across a building. A few splits this year typically mean more next year, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.

Your questions answered
Is a smaller place like Letham outside your area?
Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.
Can the sealant on our Letham premises match the finishes?
Yes, we can normally get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.
What do you need from us to quote?
Photos, drawings or a schedule of the joints are typically enough to start through the quote form on this site. If a visit is needed we’ll book one, and a fixed quote follows.
Can you take on work for an FM or managing agent?
Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What site paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
