Timber glazing upgrades in Portsmouth
Slim Cavity Units around Portsmouth is a different job from one street to the next. Property here runs to naval-era terraces, New Forest timber-framed cottages and 1960s coastal estates, and each of those brings its own set of dimensions. Locally you are contending with high wind-driven rain off the Solent, so water ingress at head and jamb on exposed south-west elevations is the fault we are called out to. This is really a job about narrow cavities that perform while keeping the sightline historic.
The survey happens before manufacture, which is why our units fit without packing or trimming. Photographs and approximate sizes are all we need to start.
Local factor worth flagging early: conservation stock in Winchester and Lymington usually requires slim-profile glazing.

Verified client, HampshirePortsmouth questions
Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
