Mastic sealing in Lower Green, done properly
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. Site teams most often ask us about repeated reactive repairs to the same buildings and water getting in round frames after rain, on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms. One point of contact handles commercial sealant work in Lower Green from the first photos to the final walk-round, whether it’s one building or several.
Around smaller places like Lower Green, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Lower Green are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- 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.

Why act early in Lower Green
A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. Around Lower Green, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Should maintenance staff do it?
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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
FAQs: Lower Green
Do you work for managing agents with blocks near Liss station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is a smaller place like Lower Green outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
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 if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Ask residents or tenants to report leaks and draughts early
- Prioritise elevations facing the weather
- Have the asbestos survey to hand for older buildings
- Share your contractor requirements early
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Mastic sealing around Lower Green: how the place shapes the job
Rainfall across the South East, Lower Green included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. At about 47 miles from central London, Lower Green is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
For owners of several units at places like Ham Barn Business Park, which lies east of Lower Green, one programme can deal with frame and external mastic across the lot. Churches, halls and community buildings such as Church of St Peter and St Paul are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Blocks of flats and mixed-use buildings often cluster around stations such as Liss station (to the south-east of Lower Green) and their window and balcony mastic tends to age at the same rate across a building.
