About construction mastic in Midlothian
Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Midlothian, send drawings through our quote form, or phone or email us to talk it through. We work on internal decorators’ caulk, sanitary and kitchen joints and cladding and panel joints, and what we’re called in for most is internal caulk splitting as the building dries out and existing joints on a refurb that need cutting out and resealing.
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
What you will pay
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Around Bonnyrigg
We work on buildings around Bonnyrigg Parish Church, Lasswade High School Centre and Public Library, among other places. Bonnyrigg’s nearest station is Eskbank station, roughly 1.1 miles north-east of the centre. Well-known places in the area include Dalhousie Castle (1.2 miles south-east) and Midlothian Community Hospital (0.8 miles north-east). Green spaces nearby include The New Leaf Co-op and Edgelaw Reservoir.
Construction mastic across Midlothian: the area picture
Across Midlothian, including Bonnyrigg, Dalkeith and Penicuik, construction ranges from housing and schools to offices, units and refurbishments. We seal perimeters, facade joints and internal sealant to the specification, on programme.
The west of Scotland is wetter than the east, but external sealing anywhere in Scotland needs a dry joint and the right temperature, so we keep some flexibility in the dates. In the parts of Midlothian near the sea, the elevations facing the weather are where sealant gives up first.
Bonnyrigg: When a school such as Lasswade High School Centre is extended or refurbished, the mastic package is often squeezed into the holidays. When a college such as Edinburgh College - Midlothian Campus (1.2 miles north-east of Bonnyrigg) builds or refurbishes, the mastic package typically has to fit around students and staff.
Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple and a consistent finish.

After the work
For the best life from the joints:
- Plan external elevations with the weather in mind
- Get the mastic subcontractor involved early in the programme
- Keep product details for future maintenance
- Ask installers to correct oversized gaps first
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault which is why protection after sealing matters.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.
What we’re called out for in Midlothian
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
These are often picked up first by site or facilities staff:
- Sealant knocked or painted over by other trades
- New external sealant already peeling away
- Frame perimeters left unsealed or poorly sealed
- Perimeter gaps outside the sealant’s range
Surface by surface
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control and we install what’s specified.
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies, and seal only with a dry joint inside the product’s temperature range.
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- The total length or number of joints
- Location, for remote and island sites
- Whether the work must be split into stages
- Joint width, depth and condition
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- What the building is and how it’s used
- The product your specification calls for
- Your programme or deadline
- The asbestos register, for older buildings
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Midlothian: questions and answers
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do your applicators hold CSCS cards?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.
