Why deal with it now?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. For buildings around smaller places like Larkfield, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

How we handle mastic sealing in Larkfield
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. We work on shopfronts below residential blocks, window and door perimeters on blocks and external wall and movement joints, and the usual reasons a site gets in touch are complaints coming in block by block and damaged joints in communal entrances and corridors. Whether you call it commercial sealant work, mastic application or joint sealing, in Larkfield it comes down to the same thing: the right product in a properly prepared joint.
For buildings around smaller places like Larkfield, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Other services in Larkfield
Do you need mastic sealing in Larkfield?
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
These are often picked up first by site or facilities staff:
- Draughts at frames across a block
- Patchy repairs in mismatched sealant
- Brittle perimeter mastic across a building
- Estate-wide sealant that is simply worn out
If your remit includes a building such as Brookfield Junior School, frame and door mastic can be programmed for the holidays.

Your questions answered
Can you work in a care home near Larkfield with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Can you work at a site such as New Hythe Business Park, by Larkfield?
Yes, sites like New Hythe Business Park are within our area, along with the rest of Larkfield. Photos and a short description are enough for a first look.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
What will the job cost?
There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Share your contractor requirements early
- Start inspections with the most exposed faces
- Check sealant joints during planned building inspections
- Log resealing dates block by block
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.

For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. Larkfield is in the South East, one of the UK’s drier regions.

General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. If others near Larkfield need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- 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.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Agree which areas must stay open
- Let building users know which areas are affected
- Arrange parking or a loading space
