Advice
Construction mastic in Lower Green
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. We work on floor and skirting junctions, sanitary and kitchen joints and internal decorators’ caulk, and the usual reasons a site gets in touch are frame gaps too wide for sealant alone and bath and shower joints scraped during the final clean. Facilities teams, main contractors and managing agents in Lower Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For a site near Lower Green, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

FAQs: Lower Green
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. Good photographs up front let us bring everything on the first visit.
Is hospital work, at somewhere like Petersfield Community Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
How long does a typical visit take?
It depends on the scope, but the work typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we will set out a timescale with the quote.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Commercial clients in Lower Green
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Leave it or put it right?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. Snagging can be priced as a separate stage. Converted and older buildings near places like Lower Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

When to call us in Lower Green
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Look out for the following:
- Bath and shower joints scraped during the final clean
- Missed perimeter joints on a new elevation
- New external sealant already peeling away
- A long mastic snag list close to completion
On a healthcare site such as Petersfield Community Hospital, 4.1 miles to the south of Lower Green, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Before you book anyone
- Whether their applicators hold CSCS cards
- What level of public liability insurance do they hold?
- Their approach to joint depth and backing
- How the joint faces will be prepared and primed
Looking after the joints
Once the work is signed off, these steps help:
- Record the products used in the O&M file
- Ask for joint and product checks before the package is urgent
- Bring the mastic contractor in after the last trades are through
- Check frame gaps are within the sealant’s range before sealing
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.

Building and refurbishing in Lower Green
At about 47 miles from central London, Lower Green is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
Units on estates such as Ham Barn Business Park, 1.5 miles east of Lower Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
