Custom Mouldings Made Simple, What You Need Before Requesting a Quote

Custom Mouldings Made Simple, What You Need Before Requesting a Quote

How to Get a Quote for a Custom Moulding

This guide explains, in plain terms, what you need to prepare so we can price a custom moulding correctly and without delays. No technical background required.

Custom mouldings are made specifically for your project. Unlike off the shelf products, nothing is assumed. The clearer the information you provide, the faster and more accurate the quote.

Step 1. Understand What a Custom Moulding Is

A custom moulding is a profile made to your exact shape and size. It can be used inside or outside and can be decorative, functional, or both.

Common examples:

  • Ceiling coving made to a specific height or projection

  • LED coving designed for a particular light strip

  • Exterior cornice or band around a building

  • Window or door surrounds matched to existing architecture

If your project does not match a standard product on our website, it is treated as custom.

Step 2. Decide Where the Moulding Will Be Used

Tell us where the moulding will be installed. This determines material, durability, and finish.

You only need to state:

  • Interior or exterior

  • Ceiling, wall, window, door, or facade

  • Decorative only or also functional, for example hiding LED strips or shedding rainwater

This information allows us to select the correct production method.

Step 3. Show Us the Shape You Want

We need to understand the shape of the moulding when viewed from the side. This is called the profile.

Best option:

  • A simple drawing or sketch showing the shape and dimensions

This does not need to be professional or technical. A hand drawn sketch with measurements is enough.

Other acceptable options:

  • A photo of an existing moulding with dimensions written on it

  • A reference to one of our standard products with clear notes explaining what should be changed

If no visual reference is provided, only very small changes to existing profiles are possible.

Step 4. Provide Basic Measurements

Measurements tell us how large the moulding will be.

Required measurements:

  • Height, how tall the moulding is

  • Projection, how far it comes out from the wall or ceiling

Optional but helpful:

  • Flat areas that touch the wall or ceiling

  • Space needed for LED strips if applicable

  • Any slope required for water runoff on exterior mouldings

All measurements are in millimetres.

Step 5. Tell Us How Much You Need

Quantity affects price and production setup.

Important production rule:

  • All mouldings are produced in fixed 2 metre lengths

What you need to provide:

  • Total length needed in metres

We will:

  • Round the quantity up to full 2 metre lengths

  • Advise if extra allowance is recommended for cutting and fitting

The minimum order is 2 metres.

Step 6. Mention Corners, Ends, and Special Pieces

Straight lengths are not always enough.

Tell us if your project needs:

  • Finished ends on the left, right, or both

  • Internal or external corners

  • Window or door surrounds

  • Decorative blocks such as keystones or quoins

Each of these is made separately and must be included in the quote.

Step 7. Material Selection, No Technical Knowledge Required

You do not need to choose a material yourself.

We offer:

  • Lightweight XPS for interior and LED applications

  • Premium EPS plaster coated mouldings for maximum durability, including exterior use

Simply describe your project and environment. We will recommend the correct material automatically.

Step 8. Confirm Paint and Finish Expectations

All mouldings are supplied ready to paint.

Let us know:

  • Interior or exterior paint

  • Any special finish expectations

No paint is applied before delivery.

Step 9. Provide the Delivery Postcode

Delivery cost depends on location.

Required:

  • Full delivery postcode

  • Country and region

This allows us to calculate transport cost and lead time accurately.

Step 10. What Happens After You Send the Details

Once we receive all information:

  • We review the profile and measurements

  • We confirm feasibility and material

  • We calculate production and delivery costs

  • We issue a clear, itemised quote

Incomplete information slows this process and may lead to assumptions that increase cost or require revisions later.

Summary Checklist

Before contacting us, prepare:

  • A sketch, photo, or reference showing the profile shape

  • Height and projection measurements

  • Total length required

  • Any corners, ends, or special elements

  • Where the moulding will be used

  • Delivery postcode

This is all that is required to receive an accurate custom moulding quote from Homemerce.

Interior Coving Installation Guide

Installing interior coving is one of the most effective ways to upgrade a room, creating a clean transition between walls and ceilings while adding architectural detail. Modern EPS and XPS covings are lightweight, easy to cut and designed for straightforward DIY installation, even for first-time users. With the right tools, correct adhesive, and a clear installation process, you can achieve a sharp, professional finish without specialist skills.

This tutorial walks you through the full installation process for interior covings, covering both plaster-coated EPS covings and smooth XPS polystyrene covings. You will learn how to measure and cut accurately, fix coving securely, finish joints cleanly and prepare the surface for painting. The guide also includes practical LED lighting tips and long term maintenance advice, making it a complete reference for installing interior coving correctly the first time. 

 

Premium EPS Covings Installation

 

🛠️ Tools and Materials Needed

  • EPS plaster-coated coving
  • Solvent-free adhesive
  • Mitre saw
  • Acrylic caulk or filler
  • High-grit sandpaper (120+)
  • Water-based paint (2–3 coats recommended)
  • Measuring tape and pencil
Recommended Adhesives

🧱 Step-by-Step Installation Guide

 

  1. Measure and Cut: Measure your wall lengths and cut coving to size. Use a mitre saw for precise cuts.

 

  1. Apply Adhesive: Spread a generous layer of solvent-free adhesive across the back of the coving for full coverage.

 

Applying Adhesive
  1. Fix in Place: Press the coving into the wall-ceiling joint and hold briefly to secure the bond.

 

  1. Seal Joints: Fill any visible joints or gaps using acrylic caulk or filler. Smooth with a damp cloth or finger.

 

  1. Sand Smooth: Once dry, gently sand the filler and surface for a flawless finish.

 

  1. Paint: Apply 2–3 coats of water-based paint for a crisp, long-lasting result.

 

Cutting Coving

 

💡 LED Lighting Installation Tips

 

  1. LEDs can go directly onto the coving. There is no need for extra layer of aluminium tape, nor paint.

 

  1. Holes for GU10 bulbs are NOT pre-cut. They need to be cut on site.

 

🧼 Maintenance Tips

 

  • Cleaning: Wipe coving with a damp cloth to remove dust. Avoid harsh chemicals.
  • Repairs: Minor chips or cracks can be filled, sanded and repainted easily.

 

XPS Coving Installation

 

🛠️ Tools and Materials Needed

 

  • XPS polystyrene coving

 

  • Solvent-free adhesive

 

  • Mitre box and saw or snap-off knife

 

  • Acrylic caulk or filler

 

  • High-grit sandpaper (120+)

 

  • Water-based emulsion paint

 

  • Measuring tape and pencil

 

 

Recommended Adhesives

🧱 Step-by-Step Installation Guide

1. Measure and Cut

Measure each wall and cut the coving to size using a mitre box and saw or snap-off knife. For corners, use precise angles.

2. Apply Adhesive

Spread a generous, even layer of solvent-free adhesive along the back of the coving. Ensure the adhesive covers all edges that will touch the wall and ceiling.

3. Position the Coving

Firmly press the coving into place at the ceiling-wall joint. Hold it for a short while to ensure the adhesive bonds correctly.

4. Fill Joints and Gaps

Smooth over any visible joins or small gaps using acrylic caulk or filler. A damp sponge or cloth can help you achieve a seamless finish.

5. Sand Smooth

Once dry, lightly sand the filled areas using high-grit sandpaper to prepare the surface for painting.

6. Paint the Coving

Remove dust and apply 2–3 coats of water-based emulsion paint. Priming is not necessary, though optional depending on the finish you prefer.

 

💡 LED Lighting Installation Tips

 

If you're incorporating LED lighting with your coving:

 

  • Maintain a Gap: Leave at least a 3cm gap between the coving and the wall or ceiling. For stronger light diffusion or wider LED strips, 5cm or more may be ideal.

 

  • Light Blocking Options: ✅ Most Recommended
    • Option 1 – Apply Aluminium Tape: Line the back side of the coving (where LEDs will shine) with aluminium or blackout tape. This is the most effective and mess-free method to prevent light bleed through the coving.
    • Option 2 – Paint the Inside Dark: Before mounting, coat the inner rear surface of the coving with a dark paint (e.g. grey or black). Then apply your final colour. It's best to test this on an offcut to ensure there's no visible impact on the finished look.
    • Option 3 – Multiple Coats of Paint: Simply paint the coving with several coats until the surface becomes opaque. This is a good fallback but may require more time and paint.

 

  • Final Finish: Regardless of the light blocking method, a couple of coats of quality water-based paint will ensure a clean, consistent appearance.

 

 

🧼 Maintenance Tips

 

  • Cleaning: Dust occasionally with a soft, damp cloth. Avoid abrasive cleaners or solvents.

 

  • Touch-ups: Small chips or marks can be filled, lightly sanded, and touched up with paint to restore a flawless look.
