How To Install Moulding - Easy Basics

Adding moulding to your rooms is one of the most rewarding projects because new moulding and trim are so visual. We have included download PDF instructions in case you need more detail and like to have a printed document in hand. You can add your own how-to tips at the bottom of this article. If your projects have been limited to hanging pictures and adding drawer pulls, talk to one of our experts when you select your new moulding or want to match existing moulding. This is not a difficult improvement if you follow instructions. If you have a friend or relative who has more experience fixing and upgrading than you do, this is the time to ask for help.

With help from Kelleher Moulding featured at Dolan's 

Mouldings Mouldings are practical. They connect different elements of a room like wall surfaces to flooring, and door and window openings. Chair rails and base mouldings protect walls from surniture and other kinds of wear. Mouldings and trimwork provide rooms with a finished look and enhance style and your own aesthetic statement.

We are proud to feature a wide variety of Kelleher moulding in both styles and materials. See some of the best designs in "Moulding & Trim" in our PRODUCTS section of this web site.

If you are fixing moulding that is no longer current, we can match it in both style and material. Ask one of the helpful Dolan's experts.

So, let's get started with the basics that will help you install crown Moulding, baseboards and more.

1. You only need a few tools.

  • Miter box
  • Mitre saw, hand or power
  • Coping saw, may be required
  • Hammer Nail set (a pneumatic nailer is recommended)
  • Finishing nails
  • Pencil
  • Sand paper
  • Tape measure
  • Wood putty

2. Select your moulding. See a sampling of what's available in the product section of this web site. Better yet, visit Dolan's and get a good look at the preferred samples. From plain and simple to elaborate -- Contemporary to Victorian -- Craftsman to Neo Classical, we offer every possible style for every application.

3. Don't forget to bring your measurements. For each length of wall space, add one foot. For a 15' wall purchase 16' of crown or baseboard. For door and window casings that will be mitered at both ends, add an amount equal to the width of the moulding to each end. If mitering will occur at one end only, the add the width of the moulding for one end only.

4. Remove existing moulding if necessary. Use a utility knife to score the seems where the casing meets the wall where there may be paint build-up and caulking. Use a pry bar or sturdy putty knife to separate casing from the wall material then use a pry bar or hammer to remove the casing. Good idea to place a piece of scrap wood on the wall material to avoid damage from your tools. On doors and windows with stools, aprons, blocks or other trim, remove the casings first, followed by aprons, then stools or other trim.

5. Miter your mouldings. Open this Kelleher HOW-TO MITRE MOULDINGS - pdf document. Mitering is a basic operation . Most joints are 45 degree angles. Moulding is either placed flat on the bottom of the miter box or against the back, depending on how the mouldings will be used. Each of the two mouldings are trimmed at opposite 45 degree anglesl When fitted together, they form a 90 degree right angle. For tight joints, nail and glue, then countersink the nails.

6. For a tighter, more foolproof joint, consider coping. Open this Kelleher HOW-TO MAKE COPING CUTS - pdf document. A scarf joint is used when you need to connect two pieces of moulding on a long wall. Both pieces are cut at 45 degree angles so they butt together at an angle.
