About our construction mastic in Princelett
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you’re dealing with sealant knocked or painted over by other trades and failed sealant in an existing building being refurbished, we can help. Facilities teams, main contractors and managing agents in Princelett tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In the countryside around places like Princelett, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Why act early in Princelett
Sealing over damaged or contaminated new joints might save a day, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. We cut out and redo the joint properly. Around Princelett, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- Commercial sealant work since 2005
- One phone line for London, the South East and Scotland
- Joints cleaned back to sound surfaces
- A Constructionline member, so easy to vet

Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
When to call us in Princelett
Value-engineered products sometimes end up in the wrong joints. 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.
What tends to prompt an enquiry:
- Window and door perimeters that won’t pass inspection
- Inconsistent sealant finishes from plot to plot
- Failed sealant in an existing building being refurbished
- Early adhesion failures on new external joints
Historic houses such as Haseley Manor, 1.8 miles to the north-west of Princelett, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

- Do they follow the manufacturer’s priming guidance?
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Glazing units that are cracked or misted
- Frame gaps too wide for sealant, which the installer needs to correct
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think.

Questions we are asked in Princelett
Is a smaller place like Princelett outside your area?
Not at all. Princelett is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you take on a job at a hospital such as Arthur Webster Memorial Hospital for Children?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What joints do you seal on a new build?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens in one fixed quote.
What happens if the weather stops external sealing?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. External work is sequenced with some flexibility.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Jobs in and around smaller places like Princelett are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we’ll be in
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Construction mastic around Princelett: how the place shapes the job
Princelett is within about 2 miles of the coast. 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. 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 we time external mastic for dry faces and agree it with the site team.
For contractors at a school such as Sandown Bay Academy, sealing has to be finished before term starts. For a contractor at a hotel such as Apse Manor Country Hotel, which lies south of Princelett, the mastic often has to be finished before a reopening date.

What the job involves on each surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer.
