How we handle construction mastic in Farnham Common
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. New and existing joints then get the same preparation. If you have sanitary sealant damaged by following trades and new external sealant already peeling away, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Farnham Common is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Farnham Common, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email us and we’ll arrange a return visit.

How the job changes by surface
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.
Building and refurbishing in Farnham Common
Farnham Common is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Farnham Common is about 23 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
Older buildings in the area around Farnham Common, such as Cliveden, which lies west of Farnham Common, need care when sealed: the product has to suit soft or historic materials. For a contractor working at a hospital such as Spire Thames Valley Hospital, 2.1 miles south-east of Farnham Common, perimeter and facade sealing is planned around patients and deliveries.
Farnham Common is about 3 miles north of Slough, in Buckinghamshire. Anywhere in SL2, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 308 places in Buckinghamshire. Our Reading page has more on work in that area, about 17 miles away.

Leave it or put it right?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we’ll tell you. Converted and older buildings near places like Farnham Common tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What you get with us
- Matching to RAL references, product permitting
- Constructionline member for supplier checks

- One contact handling all your sites

When to call us in Farnham Common
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink and internal caulk in a moving joint is usually the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
Site and facilities staff are often the first to spot these:
- New external sealant already peeling away
- A long mastic snag list close to completion
- Sealant knocked or painted over by other trades
- Frame perimeters left unsealed or poorly sealed
For a contractor at a hotel such as Pinfield Boutique Hotel (0.7 miles north-east of Farnham Common), the mastic often has to be finished before a reopening date.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
- How the existing material will be dealt with
- What the guarantee covers, and for how long
Should maintenance staff do it?
For most general trades, sealant is a sideline. 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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Deciding which fire-stopping product a penetration needs
- Joint design decisions that belong to the architect or engineer
If you are not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Questions about Farnham Common
Can you take on a job at a hospital such as Spire Thames Valley Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does your area include sites such as Slough Trading Estate, near Farnham Common?
Yes, sites like Slough Trading Estate are within our area, along with the rest of Farnham Common. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
