Why should I go with We Do Soundproofing?
We offer unrivalled advantages to the services offered by our competitors.
- Our service is backed by Qualified Acoustic Professionals, with a combined experience level of nearly 30 years working in the Construction Industry with Architects and Contractors on some of the largest and most exciting projects in the country.
- We are the only soundproofing company to offer before and after sound insulation testing. This means you will understand exactly what difference our work has made to a soundproofed wall or floor. We are currently offering our before and after standard testing service for FREE* when an order is placed with us.
- As well as the soundproofing service, our team of Contractors can provide all kinds of related services, so we can provide you with a finished room, ready to use when we leave.
- Because of our specialist acoustic background, we can provide design advice, solutions and products relating to all areas of acoustic control, which includes (but is not necessarily limited to):
- Controlling external noise coming in through a building facade or roof, including specification and sourcing of glazing units
- Specification and sourcing of reverberation time control treatments, e.g. where rooms may be used for music or speech
We have successfully helped many pleased Customers with their soundproofing and other general building work, and are still building our portfolio. We are members of Checkatrade, so we have a reviews page there. Please feel free to have a look.
If you are happy with our price quotation, just let us know and make a deposit of 50% of the overall value (including VAT), including all options. This will be taken as your order, and will cover the initial material costs on the project. We will be in touch to arrange a date to get started on improving your property, and to arrange the sound insulation test, should you want to take us up on this service.
Rude! Of course we do. We will give you and your property the respect you deserve, and if you have selected the plastering and painting options, your property will be ready to enjoy again as soon as we have left.
Sound insulation testing is a specialist form of scientific testing to determine how much sound is reduced by the presence of a solid partition, such as a floor or a wall. It is carried out in two forms: airborne and impact testing. Airborne testing is carried out on both walls and floors, and impact testing is carried out on floors only.
The results are derived in decibels (dB), and a large number of metrics are used to describe the sound reduction of a partition.
For Part E of the Building Regulations, there are different requirements for the sound insulation of partitions, and the required performances depend on the type of dwellings being tested. For example, for a party wall between two semi-detached houses, the minimum modern performance requirement is 45 dB DnT,w+Ctr (and yes, each letter in that metric means something!)
Don’t worry though, it’s ‘non-destructive’, so you wouldn’t know we’d ever been there.
Airborne sound insulation is the measure of how much a partition (a wall or a floor) can reduce sound that travels through the air, e.g. sound produced by a television, a sound system, people talking, a baby crying.
A high level of sound is made on one side of a wall or a floor, and a series of measurements then made in the same room and the room on the other side of the partition. The resulting corrected differences then provide a result.
Impact sound insulation is the measure of how much a floor can reduce sound created as a result of impacts directly upon the structure, e.g. footfalls, chairs scraping.
Impact sound insulation testing seeks to replicate impacts on a floor, and a series of different measurements are made in the space below the floor.
Sound insulation testing can be reasonably quick to carry out, provided we have everything we need at the time.
We will need access to both sides of the partition(s) we are testing, e.g. if we are testing a party wall between your living room and your neighbour’s living room, we will need to access to both your property and your neighbour’s property. We of course understand if you and your neighbour are not on good terms though (especially if there is a noise issue) and that we cannot access their property, but this will mean we cannot carry out testing.
Doors and windows will all need to be installed and closed during testing.
As airborne sound insulation testing involves high sound levels being generated in your home, the immediate area will need to be clear of anyone not involved in the testing. Additionally, one part of the testing requires only one person in the room at a time. For certain parts of the testing, we need quiet conditions!
We would need access to power sockets within the space(s) that we are testing.
If you are a Private Customer, when you come to sell your property, the test certificate we provide can be used to demonstrate that the work done meets the requirements of Part E of the Building Regulations for party walls and/or floors.
If you are a Commercial Customer or Property Developer, the test certificate can be submitted to the Building Control Approved Inspector to demonstrate that the requirements of the Building Regulations have been met. Our Consultants and Operatives have lots of experience testing large and small residential developments, and working to determine issues that could cause failures on site. Our Consultants have a proven track record in eliminating issues and working with Contractors to achieve passes.
The amount of improvement that we expect is going to be difficult to quantify without understanding the construction of your partition and the current sound insulation performance. Without sound insulation testing therefore, it would be disingenuous to provide a differential value, as many factors can affect the overall performance. It is for this reason that we always recommend taking up our free before and after sound insulation testing service.
Flanking sound transmission is sound that travels between rooms through all the structures AROUND the wall or floor we are dealing with. For example, if a wall is built up to a brick facade, sound will travel along that facade across the wall. When designing new buildings, this must all be taken in to account and measures applied to minimise its effects, which if done badly can mean the wall or floor can fail the sound insulation requirements.
Flanking sound can be a complex area when dealing with existing properties, especially with older properties. To be absolutely sure that flanking sound is going to be sufficiently controlled, we would need to have a relatively detailed understanding of the composition of the building, in terms of the way that the floors and facade interact with the internal walls which can vary greatly. The additional difficulty is that retro-fitting elements to lessen flanking sound is impractical, and that ideally flanking control would have to have been built in to the structure from the outset.
What we would advise though is to leave this to us, and to take us up on our sound insulation testing option as this will help us identify any potential issues that may arise due to flanking sound transfer. We can then consider the overall effects of any flanking issues (if there are any).
It’s entirely up to you. We can either remove sockets and switches, reinstall the existing ones to the new wall lining or change them for others. Just let us know.
Again, this will be up to you. You have two options available to you: we can attempt to lift and retain your existing finishes and then relay them on completion, or you can source a new finish of your choice and we can lay this for you. We can discuss this in more detail with you before we start work.
Please bear in mind that while carpet might be relatively easy to lift and keep in one piece, other types of flooring such as vinyl or linoleum can tear quite easily when they are lifted. We will do our best to protect your existing floor covering if you choose to retain it, but we cannot be held responsible if it becomes damaged through the process of removal.
We Do Soundproofing is relatively unique amongst soundproofing companies, in that we offer plastering and painting services. Should you want to take up the plastering and/or painting (for an additional price), we can leave you with a finished room, ready to go.
Any skirting and coving that we remove in the process of the project will be re-installed or replaced, depending on your needs. Just let us know what you would like to do.
Our excellent site team can carry out a multitude of tasks. If you’re looking to get other bits of work done that are unrelated to the soundproofing work we’re doing, just ask, and we’ll see what we can do.
*Our Standard Testing Service is free, when an order is taken out with us. Alternatively, testing is available as a refundable service cost, where the pre-paid cost for the testing is deducted from the full contract amount on completion. This assumes that you would prefer to have the testing done before placing an order with us for soundproofing works.
There is an associated charge with our Accredited Testing service, details of which can be provided on request.
