Mastic sealing near Grantshouse
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Aftercare for building managers
To get the most from the new sealant:
- Share your contractor requirements early
- Keep bins and bikes away from communal door frames
- Encourage occupiers to report problems at frames
- Check the asbestos register before any old mastic is disturbed
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
About our mastic sealing in Grantshouse
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks, and what we are called in for most is cracked, hardened mastic round windows on a block and water getting in round frames after rain. A specialist sealant contractor works differently from a general builder: on jobs in Grantshouse, preparation and product choice get the time they need.
Around Grantshouse, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Blocks and managed buildings in Grantshouse
Grantshouse is in the east of Scotland, which is drier than the west. Cold mornings still limit when outside mastic can go on. Programmes allow for that
Churches, halls and community buildings such as Grantshouse Church (Church Of Scotland) are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Buildings close to stations like Reston station, 4.6 miles south-east of Grantshouse, are often flats over shops, with frame mastic to keep sound.

Leave it or put it right?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Grantshouse, a repair visit takes planning, so it’s better to act early.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Grantshouse, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.

Before we start on site
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work

Grantshouse: questions and answers
Can you quote for a block close to Reston station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Is Grantshouse too far out for you?
Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can people stay in the building while you reseal?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Can you seal joints high up on a block?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
