Construction mastic for commercial buildings in Somerley
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list. We seal so the snag list stays short. We work on window and door perimeters, sanitary and kitchen joints and brick and block movement joints, and what we are called in for most is early adhesion failures on new external joints and a mastic package split between trades with no clear owner. Searching for sealant specialists in Somerley? We have been sealing commercial buildings since 2005.
Around smaller places like Somerley, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Ask cleaners to use soft cloths around fresh sealant
- Use the product the specification names
- Get the mastic subcontractor involved early in the programme
- Protect sealed areas from following trades
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
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.

Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes whatever the programme allows, since the work follows the trades as areas are released, and we clear our waste as we work. For work around Somerley, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- 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.
Preparing the site
- Warn occupants and staff about the work
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
Quotes
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.

Building and refurbishing in Somerley
Somerley lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Somerley included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
When a school such as Birdham CE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New wings at hospitals like St Richard's Hospital (to the north-east of Somerley) bring long runs of window and panel joints to seal.

When to call us in Somerley
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
It’s worth sending us details if you spot any of the following:
- Inconsistent sealant finishes from plot to plot
- New external sealant already peeling away
- Missed perimeter joints on a new elevation
- Sealant knocked or painted over by other trades
Recladding or extending a unit at a site like Enborne Business Park, 2.8 miles to the south-east of Somerley, brings panel joints and frame perimeters into the programme.
What to look for in a quote
- The named product and why it was chosen
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?
- Their approach to joint depth and backing
Different surfaces, different methods
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.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
