Quite possibly the most cost-effective way to overhaul a room and solve boring wall problems, PVC casing can make a big impact for less. PVC moulding is water-proof, rot, and termite resistant, making it extremely durable with minimal upkeep. Great for use over panelling edges or framing out recessed designs on the wall, because it cuts like real wood without splintering or cracking and it does not require any special tools.
