About our mastic sealing in Locksbottom
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. If you’re dealing with occupiers reporting cold air round windows and movement joints with sealant missing, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Locksbottom it comes down to the same thing: the right product in a properly prepared joint.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Why deal with it now?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Building owners, agents and FMs in Locksbottom
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Locksbottom can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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 sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- 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.
What we need from you
- Tell staff and tenants when we will be in
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work
Getting a fixed quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

What else we do in Locksbottom
What we are called out for in Locksbottom
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.
If one of these sounds familiar, it’s time for a closer look:
- Damaged joints in communal entrances and corridors
- Draughts at frames across a block
- Water getting in round frames after rain
- The same joint failures repeated across a portfolio
Older community buildings, St Paul among them, often have frames of mixed ages whose mastic varies.
Before you book anyone
- Proof of insurance
- Which product they’ll use, and why it suits the joint
- Can the work be phased to keep areas open?
- How the joint faces will be prepared and primed
Looking after buildings in and around Locksbottom
There are 10 care or nursing homes within about 2 miles of Locksbottom. Owners of care premises can bring window and door mastic into a phased programme planned around the home. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We fit the programme to your notice periods.
With historic buildings such as Down House (2.7 miles south of Locksbottom) in the wider area, owners of older properties around Locksbottom should expect mastic to need a product that suits old masonry. If you own or manage units on a site such as Glebe Farm Business Park (2 miles south-west of Locksbottom), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Landmarks near Locksbottom
Locally, jobs take us to sites close to South Park and Darrick Wood School, among other places. For rail, the closest station is Orpington station, roughly 1.2 miles east. A little further out are Princess Royal University Hospital (0.5 miles south-west) and Crofton Roman Villa (1.2 miles east). Not far away are Summer Hill and Downe Bank Nature Reserve.
After the work
A few simple habits keep the new joints working:
- List the paperwork your organisation requires when you send details
- Include mastic in your cyclical inspections
- Make it easy for occupiers to report draughts
- Reduce knocks to communal area joints
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
