HHI PVC ‘One Piece’ Cover Sills provides an alternative solution to traditional concrete sills. Our PVC cover sills address the issues of old and deteriorating concrete sills and have gained popularity as a replacement for traditional materials due to their low maintenance requirements and resistance to elements like rust and flaking paint as well as offering benefits such as improved appearance, durability, a 10-year guarantee, and a hassle-free installation process. HHI Sills are more cost-effective in the long run compared to completely replacing concrete sills, which might also require additional work like re-plastering and decorating.

Remember that the longevity and effectiveness of any solution will depend on the quality of the product and the installation process. If you’re considering making a change from concrete sills to PVC cover sills, HHI is the right choice for your needs.
