Construction mastic for Arniston sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Different surfaces, different methods
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used, food-safe where food contact is possible.
Snagging before handover
Snags typically come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
How we handle construction mastic in Arniston
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal areas can typically carry on while the outside waits. Most enquiries involve inconsistent sealant finishes from plot to plot and frame perimeters left unsealed or poorly sealed, on cladding and panel joints, internal decorators’ caulk and sanitary and kitchen joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Arniston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
External sealing around Arniston depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What else we do in Arniston
What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Specifying the product where the designer hasn’t
- Faulty frames rather than failed sealant
- Damage to finishes by other trades after we’ve sealed
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.
What we seal
- Sanitary and kitchen joints
- Window and door perimeters
- Cladding and panel joints
- Internal decorators’ caulk
- Brick and block movement joints
- Floor and skirting junctions
When to call us in Arniston
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink. Choosing the right product for each joint reduces that.
Things that usually lead to an enquiry:
- Inconsistent sealant finishes from plot to plot
- Frame gaps too wide for sealant alone
- Snag items on joints that need redoing before handover
- New external sealant already peeling away
Older buildings in the area around Arniston, such as Melville Castle, which lies north-west of Arniston, need care when sealed: the product has to suit soft or historic materials.
Before you book anyone
- How the joint faces will be prepared and primed
- Whether old or failed sealant will be cut out, not overlaid
- What the guarantee covers, and for how long
- Their pre-qualification and accreditations
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: 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.
Quoting for work in Arniston
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Induction, permit and paperwork requirements
- How much there is to seal
- Location, for remote and island sites
- Whether old sealant has to be cut out first
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
What to include in your enquiry
We can often quote from photos and a few details. It helps to include:
- When you need the work done
- The postcode of the building
- Clear photos of the problem areas
- What the building is and how it’s used
Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email the details over.
Mastic packages on Arniston sites
Building work in Arniston comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. We seal to the specification that sits behind the warrant. Arniston is on Scotland’s drier eastern side. Cold, damp starts still stop external sealing on some days. External mastic is planned with the site manager for workable conditions.
For contractors refurbishing units at places like Butlerfield Industrial Estate, 2.3 miles to the north of Arniston, the mastic covers cladding panels, roller-door and window perimeters. Hospital estates such as Midlothian Community Hospital, 3.8 miles to the north-west of Arniston, 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.
Arniston is about 4 miles south-east of Bonnyrigg, in Midlothian. We send applicators to Arniston for mastic packages. 34 places across Midlothian fall within our area, Arniston among them. We also cover Edinburgh, around 10 miles from Arniston.

Your questions answered
Would you work within a site like Midlothian Community Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you take on work at estates like Butlerfield Industrial Estate, close to Arniston?
Yes, sites like Butlerfield Industrial Estate are within our area, along with the rest of Arniston. A few photographs and the unit address let us price the work.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
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 confirm what’s available for the specified product when we quote.
How much does the work cost?
Every job gets its own fixed quote. To get one, call 01277 525 020 or send photos by email with a description of the work.
Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Tell us who will meet us and how to get in at your building near Arniston. That goes into the plan alongside the quote.

- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.

- Final snagging is completed and the 12-month guarantee applies.
What we need from you

- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we will be in
