What should I know about roller garage doors with vision and vent laths in Penzance?
- Keep anything that must stay completely dry away from vent laths, as some moisture may get in during wet, windy weather.
- Weigh up insulation if you're choosing insulated laths, as vent laths let air through and vision laths hold less heat.
- Ask whether vision or vent laths are covered by the certificate if you're choosing a security-rated door model.
- Check the agreed position of the laths in your written quote, and again on fitting day before the installer finishes.

Rules that apply in Penzance
Planning
Replacing a garage door is not usually development that needs planning permission. Check first if your home is listed (listed building consent covers works that affect its character), sits in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.
Structural work
Widening the opening, removing a central pier or fitting a new lintel is structural work that needs Building Regulations approval from building control before it starts.
Roller garage doors with vision and vent laths in Penzance: questions
Can you remove my old garage door in Penzance?
Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Penzance address, along with standard fixings and making good to the reveals. If the frame or lintel needs work, we price it at the survey before you agree.
How long does it take to fit a roller garage door in Penzance?
Most single domestic roller doors are fitted in a day once the door has been made, including removing the old door. Wider doors, conversions that need building work and jobs where power has to be run can take longer; the quote says what to expect.
What do you check at a survey in TR18?
At a survey in TR18 we measure the width and height of the opening, the headroom above it for the roller box, the side room for the guide rails and the floor level. We also look at the lintel and where power can come from for an electric door.
How much do roller garage doors with vision and vent laths cost in Penzance?
Our guide price for roller garage doors with vision and vent laths is from £1,040 inc VAT. The figure for your garage depends on the opening size, the door specification and any extras, and is confirmed in a written quote after a free survey. The guide prices are the same in Penzance as elsewhere we cover.
Can vision laths be added to my existing roller door?
Vision and vent laths are built into the curtain when a new door is made, which is why we offer them as an extra on new doors. Changing laths in an existing curtain depends on finding compatible laths for that door, so if you want daylight or ventilation in your current garage, it's usually simplest to plan them into a replacement door.
Do vent laths let rain or insects into the garage?
Vent laths have openings by design, so some air movement comes with them, and in very wet, windy weather a little moisture may get in. If you store things that must stay completely dry, keep them away from the door. Think about where the vent laths sit in the curtain, and discuss it at the survey before you decide.
