North Fareham: questions and answers
Is a smaller place like North Fareham outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Does the sea air around North Fareham change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Can you work to our specification?
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. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How we handle construction mastic in North Fareham
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal sealing often fills those days. If you have failed sealant in an existing building being refurbished and external joints sealed in damp or cold conditions that are now failing, we can put it right, on sanitary and kitchen joints, window and door perimeters and cladding and panel joints alike. Most enquiries from North Fareham start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Construction in and around smaller places such as North Fareham is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers
To get the most from the new sealant:
- Bring the mastic contractor in after the last trades are through
- Put any product change through the designer first
- Note which sealant went where at handover
- Check frame gaps are within the sealant’s range before sealing
Record which products went where in the handover file. That helps the building owner maintain the joints later. We can confirm the handover information you need when we quote.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.

Surface by surface
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product and hygienic or food-safe grades wherever food contact is possible.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
Facades, frames and programmes in North Fareham
North Fareham lies within about 2 miles of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. North Fareham is about 64 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
On a healthcare site such as Knowle Hospital, which lies north-west of North Fareham, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Units on estates such as Fareham Industrial Park (0.5 miles south of North Fareham) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at colleges like Fareham College, 1.6 miles to the south-west of North Fareham, tend to run to term dates, so the mastic is planned tightly.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Frames fitted out of tolerance
- Rework caused by others damaging completed areas
- Specifying the product where the designer hasn’t
If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
Surfaces we seal

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
