Construction mastic for commercial buildings in Upper Lambourn
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal areas can typically carry on while the outside waits. Site teams most often ask us about mastic snags holding up handover and frame gaps too wide for sealant alone, across sanitary and kitchen joints, floor and skirting junctions and brick and block movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Upper Lambourn is the same: the right product in a properly prepared joint.
Sites around smaller places like Upper Lambourn can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Sites and facades in and around Upper Lambourn
At about 63 miles from central London, Upper Lambourn is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Upper Lambourn 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 we time external mastic for dry faces and agree it with the site team.
Hotels like The Red Lion Hotel (to the south-east of Upper Lambourn) rarely close for long, so refurbishment mastic is phased floor by floor. With historic properties like Ashdown House, 2.1 miles to the west of Upper Lambourn, in the area, refurbishment work often meets old masonry that needs compatible sealants.
Upper Lambourn is about 7 miles south-west of Wantage, in West Berkshire. Anywhere in RG17, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Rework caused by others damaging completed areas
- Frame gaps too wide for sealant, which the installer needs to correct
- Glazing units that are cracked or misted
If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think.

Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Upper Lambourn need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- 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.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements
- Send your site hours and access windows
Ask for a quote

After the work
Keep the joints in good shape with a few simple steps:
- Release areas for mastic once other trades have finished in them
- Note which sealant went where at handover
- Protect sealed areas from following trades
- Share drawings and the specification as soon as possible
Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.
Different surfaces, different methods
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. 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.
