How we handle construction mastic in Farlington
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal areas can typically carry on while the outside waits. If you have early adhesion failures on new external joints and failed sealant in an existing building being refurbished, we can put it right. For commercial sealant work in Farlington, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around places like Farlington, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
How the job changes by surface
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control and we install what’s specified.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move.
How the quote is worked out
To price the job, we consider:
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Site requirements such as inductions and permits
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
Details that help us quote
However big the job, these details speed things up:
- Whether the building will be occupied during the work
- Access details, including height
- Where the site is, with the postcode
- Rough lengths or quantities, or drawings if you have them

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Oversized gaps that need packing or adjustment by others
- Joints damaged after sign-off by following trades
- Faulty frames rather than failed sealant
If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think.

Common questions from Farlington clients
Can you work around term dates at a campus such as University of Portsmouth - Langstone Campus?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you take on work at estates like Railway Triangle Industrial Estate, close to Farlington?
Yes, sites like Railway Triangle Industrial Estate are within our area, along with the rest of Farlington. Send details of the unit and the work through our quote form for a quick quote.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Why deal with it now?
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. If the frame is life-expired, we will tell you. For buildings in places like Farlington, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Construction mastic around Farlington: how the place shapes the job
Farlington sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. A 2-mile radius around Farlington takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
When a school such as Solent Infant School is extended or refurbished, the mastic package is often squeezed into the holidays. For a contractor working at a hospital such as Queen Alexandra Hospital, which lies west of Farlington, perimeter and facade sealing is planned around patients and deliveries. Building work at universities like University of Portsmouth - Langstone Campus (3.5 miles south of Farlington) is often timed for the summer, mastic included.
