Why deal with it now?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. For buildings near Nethermill, dealing with all the failing joints at once saves return trips. Send photos and we’ll quote for everything together.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

How a job runs
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Travel to smaller Scottish places like Nethermill is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
- Let building users know which areas are affected

Questions we are asked in Nethermill
Can you quote for mastic across several buildings in and around Nethermill?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Is Nethermill off your patch?
Not at all. Nethermill is within our area. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Looking after the joints
After handover, these steps help:
- Reduce knocks to communal area joints
- Include mastic in your cyclical inspections
- Avoid piecemeal callouts where you can
- Check the asbestos register before any old mastic is disturbed
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
When to call us in Nethermill
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Any of the following is a good reason to get the joints checked over:
- Repeated reactive repairs to the same buildings
- The same joint failures repeated across a portfolio
- Old repairs sealed over failed mastic
- Water getting in round frames after rain
For a building around Nethermill, a look at every elevation first shows which joints need renewing now and which can wait.

- Whether primer will be used where the manufacturer specifies it
- What the guarantee covers, and for how long
- Proof of insurance
When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Failed window or door frames, which need a window contractor
- Substrate edges that need repairing first
If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer before you book.
Where we work in Nethermill
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks

Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
