How we handle construction mastic in Farncombe

Mastic tends to be one of the final packages before handover, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers, sealing plot by plot or floor by floor as areas are released. The enquiries we see most involve different trades sealing to different standards and perimeter gaps outside the sealant’s range, across cladding and panel joints, floor and skirting junctions and internal decorators’ caulk. Whoever orders the work in Farncombe, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

On a small site around Farncombe, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Your questions answered

Is Godalming Business Centre, near Farncombe, within your area?

Yes. Estates, retail parks and business parks around Farncombe, Godalming Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Is hospital work, at somewhere like Milford Hospital, something you do?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do your applicators hold CSCS cards?

We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.

Do you guarantee new-build sealant work?

It’s backed by our 12-month guarantee on the workmanship. Protecting sealed areas from following trades helps avoid damage.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Flag uneven or tapered frame gaps early
  • Brief following trades on areas that have been sealed
  • Note which sealant went where at handover
  • Don’t schedule sealing before decorators and flooring are done

At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. Tell us what records you need and we will confirm with the quote.

External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.

What affects the price in Farncombe

Quotes vary with the job. It mainly depends on:

  • How much existing material needs removing
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists
  • The type of building and who uses it
  • Any dates the work must fit around

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

New build and refits around Farncombe

A 2-mile radius around Farncombe takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. At about 30 miles from central London, Farncombe is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

Hotel extensions and refits, at places such as Godalming Hotel, which lies south-east of Farncombe, usually run between busy periods, so the sealing is squeezed into short windows. On a campus such as University of Surrey - Manor Park Campus (2.7 miles north of Farncombe), new teaching buildings and residences are usually built and refurbished around the academic year. Extensions at sites like Milford Hospital, 2.2 miles to the south of Farncombe, typically sit beside working departments, and the mastic follows strict access rules.

Farncombe is about 4 miles south-west of Guildford, in Surrey. Anywhere in GU7, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

Different surfaces, different methods

Window and door perimeters

Internal perimeters are usually sealed with a paintable product where decorating follows. We follow what’s specified, and colour-matched products can be used where the frame is on show.

Fire-rated sealant where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services, and we’ll tell you if the detail calls for something else. Tell us what records you need and we’ll confirm with the quote.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

What happens if it’s left?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. In a smaller place such as Farncombe, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
