Refurbishment and Relaying: Creating a Lasting and Fresh Look

The refurbishment and relaying of a floor will produce a surface to last with a fresh, new look. It also provides a great Exquisite opportunity to increase comfort in the property by introducing insulation along with soundproofing. Where moisture is an issue, damp-proofing membranes are also a valuable addition to a wooden or concrete subfloor.

Sound-Proofing Insulation

Plywood and chipboard are commonly used today where a major refurbishment requires the replacement of older subfloors. Chipboard sheeting comes in tongue-and-groove and provides a smooth and solid subfloor, similar to plywood.

Both materials offer limited soundproofing qualities. The additional fitting of rock wool insulation for properties with wooden subfloors will improve soundproofing.

The prevention of airborne and impact noise is possible with the installation of new floors, which will be laid over the appropriate underlay. Ask Sanding Wood Floors to demonstrate the choice of underlay available with increased soundproofing qualities – dependent on the nature of your subfloor, the type of flooring to be laid, and the budget.

A typical quality underlay will offer soundproofing of the airborne sound of up to 18-24 dB. Some underlays, however, will go beyond these limits. The most effective level of soundproofing comes with the double rubber E-Board product – an expensive but highly effective option.

Damp Proofing Floor Insulation

Solid wood planks can contract in response to changes in environmental humidity and temperature. Damp-proofing is therefore vital for hardwood flooring installations.

Damp-proofing is carried out by applying a liquid or plastic film over the subfloor, before laying the new floor or underlay.

Many contemporary underlay products come with a built-in DPM membrane, which gives additional protection and assurance.

Draft Prevention And Thermal Floor Insulation

Over the years, in older properties with pine board floors, gaps appear as the boards shrink. This often results in two problems: draught and cold on ground floors and increased noise transmission with upper floors.

Rockwool insulation has the flexibility and volume to allow stuffing of the
insulation between the joists. This provides a modest degree of soundproofing between the floors – and will significantly help the thermal insulation.

The fitting of such underlay may be tricky on ground floors, where there are large gaps between the joists. Some holding support for the insulation may be required, to enable it to be laid and stay close to the wooden floor. Various methods include nets or metal strings over which the insulation is laid.

Fibreboard underlay is the common choice for laminate flooring installation over floorboards. The fibreboard will significantly increase the thermal insulation on such subfloors and help to deal with minor unevenness as well, with its ideal thickness of 5.5 mm.

Which Flooring Types Go With Which Insulation?

Rockwool insulation for original pine floorboards.

If you are installing parquet flooring, you can still choose underlay if sound-proofing is essential. Parquet flooring blocks require a smooth, level subfloor – usually one covered with ply or chipboard.

Frequently Asked Questions

How does floor insulation help with sound-proofing?

Floor insulation helps reduce both impact noise (like footsteps) and airborne noise. In many London flats and terraced homes, insulation is one of the most effective ways to create a quieter living space.

Can you fit insulation without lifting the entire floor?

Yes — in many cases, we can add insulation between or under existing boards. If lifting is required, we’ll let you know during the assessment.

Will sound-proofing make a big difference in my home?

Yes, most homeowners notice a clear reduction in noise. While it won’t make any home completely silent, it significantly reduces everyday sounds and improves comfort — especially in London properties with close neighbours.

How long does floor insulation and sound-proofing take?

Most projects take one day, depending on room size and the type of floor. Larger homes or floors needing repairs may take slightly longer.

Is floor sound-proofing suitable for flats or rented properties?

Yes — it’s one of the most common services requested for London flats. If you’re renting, you may want to confirm with your landlord, but the process is usually straightforward.

How much does floor insulation and sound-proofing cost?

Costs depend on room size and the insulation method needed. You can check our prices page for general guidance or use the booking tool to request a tailored quote.

Will insulating the floor raise the height of the floorboards?

It can raise the height slightly, depending on the materials used. We’ll explain the expected height change during inspection and ensure it won’t affect doors or skirting.

Do you cover my area for insulation and sound-proofing?

We cover most of London and nearby areas. You can check the full list on our areas we serve page or call (800) 955 0015 if you’re unsure.
