What Customers Are Saying

Customers overwhelmingly praise these baseboards and trim for exceptional value, ease of installation, and attractive finish. Most highlight the primed surface allowing quick prep and often just one paint coat, plus affordability of bulk purchasing for large renovations. Reviewers consistently note the products are easy to cut and install, delivering a clean, high-end look despite the affordable price. Many appreciate the solid, durable construction and traditional style. A few report minor surface inconsistencies or warping in sun-exposed areas, but these concerns are vastly outweighed by widespread satisfaction. Overall, customers consider them an excellent choice for both DIY and professional projects.

they are baseboards and they work

Would Recommend

I bought this molding to replace baseboards after replacing the carpet with LVP. They work as expected. I sorted them by how straight they were. About half were very straight for the whole 12 feet. Others has some warping, but they worked fine for smaller lengths. Painting was a breeze.
