Mastic sealing across Catmore
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
How we handle mastic sealing in Catmore
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on communal kitchens and washrooms, window and door perimeters on blocks and external wall and movement joints, and what we are called in for most is a mix of products and colours from past repairs and complaints coming in block by block. A specialist sealant contractor works differently from a general builder: in Catmore, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as Catmore tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Looking after buildings in and around Catmore
At about 54 miles from central London, Catmore is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
For owners and agents with buildings in or around Catmore, block-wide mastic programmes deal with frames and external joints of the same age together.

Honest limits

- Broken glass or failed sealed units
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Your questions answered
What documents will you need to give us for a job in Catmore?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Can one quote cover a number of our buildings near Catmore?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can people stay in the building while you reseal?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Do you work in Catmore?
Yes. Catmore is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or send photos by email.
After the work
Once the work is signed off, a little attention goes a long way:
- Start inspections with the most exposed faces
- Ask residents or tenants to report leaks and draughts early
- Share the asbestos register when you send details
- Keep bins and bikes away from communal door frames
If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
From enquiry to sign-off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Catmore may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We check the asbestos register for older buildings and look at the joints.
