Soundproofing/Installation Guide

Electrical works

Electrical alterations to wall sockets/spotlights should be carried out by NICEIC part P qualified electrician. Unless previously agreed we would ask for the electrical works to be prepared prior to our arrival by a qualified and competent professional prior to our works being carried out for our installers to be able to complete our works in a safe manner. 


For walls and ceilings to be as acoustically efficient as possible little to no cut out of the boards will ensure a greater result. For this reason, and if it is possible to relocate any sockets, T.V aerials, data cables, phone lines to an adjacent wall then this is strongly advised. 

Where this is not possible for sockets then the following options are available for wall sockets:

Surface mounted: This option is the best alternate to relocating the sockets to an adjacent wall and will minimise the sizes of the holes in the acoustic plasterboards. The main consideration for this will be that to surface mount the boxes will require an electrical box to be fixed to the face of the plasterboards that will protrude approximately 30mm plus a socket faceplate and aesthetics should be considered. Wooden patresses that surround the sockets can be used as an options for appearance. Please see images as examples.  







Partially mounted: Both the clip and furring channel system and independent timber stud frame system require a double layer of 15mm board and 4mm membrane as the final face coverings. This means that another option for sockets is to only cut out the top layer of 15mm plasterboard so that 15mm of the 30mm socket box can be buried without the need to fully cut out both layers of the soundproofing and compromise the effectiveness of the work. This is sometimes considered a better alternative and offers some protection vs a fully recessed drywall socket box. 


Recessed socket: This option is to be avoided. Although products like putty pads are available they still lack the mass of a sealed wall and plasterboard system. For this reason we strongly advise that this should only be considered if you are absolutely sure that the loss in noise that will inevitably be lost through these large cut outs (approx 7cm x 14 cm per double socket) is the only way you would like the finished wall to appear. Although we understand that this maybe the most aesthetically pleasing the trade off with this system can be detrimental to the work carried out result in a large dB transfer through the party wall. 


Spotlights: Much like recessed sockets, spotlights can have a detrimental effect on soundproofing ceiling systems due to the amount of hole saw cuts and sizes required to house the lighting units. For this reason we strongly advise that ceilings should have any spotlights removed prior to soundproofing systems being installed and alterations made to the wiring to change to single pendant lighting. These can be used to feed lighting bars and track lighting to illuminate areas of the room. 

T.V. Brackets & Mounting. Ideally T.V's should be mounted off of your newly fitted wall to minimise sound across the structure. If you can only have the T.V mounted in this area please make us aware some can add a plywood pattress behind the wall to support the bracket.  

Plumbing & Heating

Plumbing works should be prepared prior to our arrival on site by a competent/qualified person and any particular requirements should be discussed to ensure delays are avoided.

Please inform us if you have underfloor heating or if you are aware of any water pipes that may cause issues during the installation process. 

Flooring & Furniture Prep. (Prep and protection). 

We will protect your floors in our immediate workspace and will cover the walkways into the property with a combination of roll out plastic floor covering, hardboard or recycled cardboard or Corex style protection. 

Cupboards and furniture will be covered with plastic sheeting. If any specific or additional items are required for special protective coverings please make us aware and we will be happy to help. 

Carpets, Coving & Skirting Boards

Carpets- In the case of a system being installed these will most likely be folded back to allow for the space of the new system to be installed and on completion will need to be cut to suit the depth of the new wall. (This is to be carried out or arranged by the owner/client).

For flooring installations these can either be moved to another room or rolled back half and half to allow access. 

For ceilings these can be kept in place and protected. 

Coving & Cornice -Any existing coving that is in place will need to be removed to allow for the wall system to run from floor to ceiling. This will also apply when a new ceiling system is to be installed. In nearly all cases the coving will not be salvageable. It is also recommended that these should be left off as in some cases this can bridge and channel sound once the work is completed. If you do need reinstall this then please ask for advice for the best fixing methods. 

Dot & Dab plasterboard- In nearly all cases dot and dab plasterboard should be removed as this method of fixing plasterboard to the party wall is known to be highly detrimental to any soundproofing works. 

Waste Removal

We are able in most cases to provided waste removal as either an option included into an estimate or will automatically be included as part of our service. If you would like to carry out this part of service yourself then please ask and this can be deducted from the quote. Please note we cannot deduct this once the site has been cleared. 

Post Installation Cleaning

Once the installation has been completed we will endeavour to carry out a 'builders clean' of the property. This will include the removal of any protection, hoovering and dusting. It is very likely that this will require additional cleaning in the next 1-2 days as more light dust continues to settle. This will need to be completed by the customer. 


If plastering has been arranged and agreed then this will be carried out by our team. Drying times of between 2-4 days (depending on conditions) should be factored into the whole project and any following trades or installation requirements considered in this timeframe.
