Are House Signs Weatherproof? What You Need to Know Before You Buy
It's one of the most common questions we get asked at House Sign Shop — and it's a very sensible one. A house sign lives outside 365 days a year, exposed to rain, frost, UV, and everything the British weather can throw at it. So are house signs weatherproof? The short answer is yes — but the detail matters. Here's what you need to know about each material.
Natural Slate — Built to Last Centuries
Slate is one of the most weatherproof natural materials on earth. It's been used for roofing, flooring, and signage for centuries precisely because it handles moisture, frost, and UV exposure exceptionally well. Our slate house signs are cut from 10mm thick natural Brazilian slate and sealed with a specialist finish that protects the surface and the engraved lettering.
The deep V-carved engraving on our slate signs means the lettering is cut into the stone itself. Painted colour inlays are protected within the engraved channel, making them far more durable than surface-applied paint.
Guarantee: 3 years as standard. In practice, a quality slate sign can last for many years with appropriate care.
White Corian — UV Stable & Frost Resistant
Corian is a premium solid surface material engineered for durability. It's non-porous, frost resistant, and UV stable. Our white Corian signs are designed to maintain their clean white appearance outdoors year after year.
The colour inlays on Corian signs are set into the engraved grooves rather than simply applied to the surface, helping to protect them from the elements.
Guarantee: 7 years as standard.
Reconstituted Stone (Reflective Signs) — Weatherproof & Visible at Night
Our rustic and rectangular reflective house signs are hand-cast from reconstituted stone — a dense, weatherproof material that's far more durable than painted metal or plastic alternatives. The reflective lettering is designed to withstand outdoor conditions while remaining highly visible when light is reflected back from a direct light source.
Guarantee: 7 years worldwide against deterioration due to climate conditions.
What About Fixing Hardware?
All HouseSignShop signs can be supplied with or without fixing holes. If fixing holes are chosen, the available layouts and supplied fittings vary by product. Use stainless steel screws and wall plugs appropriate for your wall type where these are required; exterior-grade screws are suitable for gate posts and timber surfaces.
