-
What warranty comes with Swallow Raven Greenhouses?
Every Swallow Raven Greenhouse includes a 12-year manufacturer warranty against timber rot and decay, plus a 3-year warranty on all fixtures, fittings, and hardware. This covers manufacturing defects and material failures but doesn’t cover accidental damage or improper base preparation. The warranty reflects Swallow’s confidence in their Yorkshire manufacturing quality.
-
Do Swallow Raven Greenhouses need wood treatment?
No regular wood treatment is needed for Swallow Raven Greenhouses. The ThermoWood construction comes pre-treated through a high-temperature process that makes the timber naturally rot-resistant. You can leave it to weather naturally to silver-grey, maintain the original honey-brown with occasional oiling, or choose factory-applied painted finishes that last 5–7 years before requiring repainting.
-
How long does on-site installation take for a Swallow Raven Greenhouse?
On-site installation takes 1–2 days depending on greenhouse size. The installation team arrives with all components pre-cut and ready to assemble on your prepared base. Your greenhouse will be scheduled for delivery and installation 8–12 weeks after ordering, with 2–3 weeks’ notice of the confirmed date. Installation is included free on all orders and covers UK mainland addresses. The service doesn’t include base preparation, which you must complete beforehand.
-
What sizes are available in the Swallow Raven Greenhouse range?
Swallow Raven Greenhouses are available in seven standard lengths: 8x4ft, 8x6ft, 8x8ft, 8x10ft, 8x12ft, 8x14ft, 8x16ft, and 8x20ft. All models are 8ft 9in (2660mm) wide with 7ft 6in ridge height. The 8x10 is the bestselling size, offering 80 square feet of growing space with room for staging on both sides and comfortable working room. Larger sizes suit extensive tomato or cucumber crops.
-
Are Swallow Raven Greenhouses better than aluminium greenhouses?
Swallow Raven Greenhouses provide 35% better insulation than aluminium frames due to timber’s natural insulating properties. This extends your growing season by 4–6 weeks at both ends and reduces heating costs for winter growing by approximately 30%. The wooden frame also looks more attractive in traditional garden settings. However, aluminium greenhouses cost £600–£1,200 less for comparable sizes and require zero maintenance. The choice depends on whether you prioritise aesthetics and thermal performance or budget and convenience. For serious year-round growing, the Swallow Raven’s insulation advantages pay dividends over its 25–30 year lifespan.
