Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Bring the mastic contractor in after the last trades are through
- Check frame gaps are within the sealant’s range before sealing
- Stick to the specified sealant rather than a generic substitute
- Plan external elevations with the weather in mind
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.
Construction mastic for commercial buildings in Dunsfold
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. We work on window and door perimeters, brick and block movement joints and internal decorators’ caulk, and the usual reasons a site gets in touch are mastic snags holding up handover and old sealant on a refurbishment that needs stripping before new work. Looking for mastic applicators who cover Dunsfold? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Conversions of older rural buildings near smaller places such as Dunsfold bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area.

- Drawings, the sealant specification and your programme come to us for pricing.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.

What the job involves on each surface
Snagging before handover
Snagging is often the final mastic stage. Snags are cleared room by room.
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product, food-safe where food contact is possible.
FAQs: Dunsfold
Is a hospital such as Milford Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like Dunsfold outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
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.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Mastic packages on Dunsfold sites
Dunsfold is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Central London is about 33 miles from Dunsfold. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
Hospital estates such as Milford Hospital (to the north-west of Dunsfold) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Units on estates such as Littlemead Industrial Estate, 3 miles north-east of Dunsfold, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility, with the same standard on every plot. Halls, stores and units around places like Dunsfold may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
