Do you have dogs or children? Is there a good chance your pets or kids might damage your trim or scratch at your baseboards? If the answer is yes, you might want to choose a solid wood material as opposed to DF.
If you have limited funds, you might opt to only add baseboard and casing, then forego other items like crown moulding, panel moulding, etc. Or maybe you choose an MDF material instead of solid wood because it’s less expensive.
We do not do installations. So, If you’re not an experienced carpenter or contractor, it may be worth it to hire a professional. You’ll need to factor that into the budget. Trust me when I say (it’s tough), so if you’re taking the DIY route, you’ll want to order plenty of overage.
