Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Surface by surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.
Construction mastic in Lightwater
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal sealing often fills those days. We work on floor and skirting junctions, cladding and panel joints and brick and block movement joints, and the usual reasons a site gets in touch are different trades sealing to different standards and sanitary sealant damaged by following trades. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lightwater, preparation and product choice get the time they need.
In a smaller place such as Lightwater, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
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’re clear about what is covered before work starts.

Construction mastic around Lightwater: points for this area
Lightwater 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 external mastic is timed for workable conditions and agreed with the site manager. Central London is about 27 miles from Lightwater. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
Building work at universities like Imperial College Silwood Park Campus (to the north of Lightwater) is often timed for the summer, mastic included. On a healthcare site such as The Priory Hospital, which lies south-east of Lightwater, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Projects at schools like Hammond School work to term dates, so mastic is programmed tightly.

Related advice
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Share drawings and the specification as soon as possible
- Brief following trades on areas that have been sealed
- Bring the mastic contractor in after the last trades are through
- Ask installers to correct oversized gaps first
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We raise them during our first walk of the area.

Common questions from Lightwater clients
Is a smaller place like Lightwater outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Would you work within a site like The Priory Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can staff carry on working while you are here?
In most cases, yes. We phase the work so most of the building stays in use.
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?
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 you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
What accreditations do you hold?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. We’re fully insured for public liability.
