The conversion of basements is becoming increasingly more popular, as the demands for more usable space, rises. Converting an unusable, damp or flooded basement, intro a dry, habitable room, can be an inexpensive way of increasing living space and adding substantial value to your home.

Basement waterproofing – the problems and solutions

Historically, home owners have neglected the damp, smelly basement in favour of building out and upwards. Unfortunately, in most cases, this will reduce valuable garden space.

Converted basements offer a wide variety of uses; additional living rooms, home cinemas, home gyms, additional bedrooms with en-suites and wet rooms, even saunas. The only limit is your imagination.

The need for a professionally, converted basement is now essential, as regional flooding has increased and the presence of groundwater can cause severe damp conditions within the basement, as well as water seepage and potential flooding.

A dry basement today, could become a wet basement tomorrow.

FAQs about basement conversions

1) What is the cost of a basement conversion?

As a general guide, a simple basement conversion (which might include the addition of a bathroom and some basic storage) could start from around £20,000.

2) What is the process of a basement conversion?

The first step in any basement conversion is to assess the space and determine what the best use of the space will be. Once that has been decided, the next step is to obtain the necessary permission from local authorities. Once the permission have been obtained, the next step is to begin any excavation works. This process can be quite involved, depending on the size and scope of the project. Once the excavation is complete, the next step is to install the necessary drainage and waterproofing systems.

3) What are the benefits of a basement conversion?

A basement conversion can offer a number of benefits to homeowners. Firstly, it can provide additional living space, which can be used for a variety of purposes such as a home office, playroom, or even an extra bedroom. Secondly, a basement conversion can add value to your home, making it more attractive to potential buyers, should you ever decide to sell up.

4) What are the risks of a basement conversion?

There are a few risks to consider when converting your basement into a living space. These risks include;

Continued water damage – if your basement is not properly waterproofed, it is at risk of future water ingress.

It is, therefore, imperative that you employ a qualified and accredited company to carry out the works.

8) What are the damp proofing requirements for a basement conversion?

All work needs to be carried out in accordance with the British Standard, BS 8102:2022, which is ‘The Code of Practice for Protection of Beloe Ground Structures Against Water Ingress’. Also, anyone who is designing the waterproofing works, or preparing a quotation for the works, should be qualified and be a Certified Surveyor in Structural Waterproofing (CSSW).

9) What are the insulation requirements for a basement conversion?

10) What are the ventilation requirements for a basement conversion?

There are a few things to consider when it comes to the ventilation requirements for a basement conversion. The first is the size of the basement, the second is the type of conversion you’re planning on doing and the third is the type of ventilation system you’ll need.

The size of the basement will dictate the amount of ventilation you’ll need. A small basement won’t need as much ventilation as a large one.

Professional from Damp Report to Final Plaster

Delighted with the service. RTC installed a damp proof course and replastering at my house. The damp survey was professional, detailed and very clear on the work to be done with good accompanying explanations of the issues. The office is easy to contact, answering all my calls and returning them promptly if the person I needed to speak to wasn’t immediately available. The technicians who performed the work were professional and worked fast and hard. They explained clearly all the steps and left the house clean every day. I am really please with the final finish and overall result. They were not the cheapest quote or survey I had, but at all steps were the most professional. Highly recommended.

The two lads who completed the work, Wes and George, were hard working, polite and answered my many questions without any problem.

Transparent Pricing & Top-Notch Workmanship

From initial contact with the office, to the visit from the surveyor, the surveyors report which was very thorough as he actually went under the floors, the price for the work and the quality of the job itself was excellent. The surveyor Sam did an excellent job as was the repairs done by Dan and Karl. After the work was completed, I was contacted by the office to check that I was satisfied with work and the quality of the job, which I was. Professional all the way through with good customer service, made to feel I was important to their business. It’s an old adage but big enough to cope and small enough to care fits the bill. Would use again and would have no reservation about recommending them.

Protected Home, Perfect Finish—Excellent Result

Originally recommended by my surveyor after discovering damp in 5 rooms. All the RTC staff were friendly and did a great job in minimising the dust and mess with protected sheeting and flooring throughout the house. The final result is excellent and a big call out to Steve for helping with moving a very heavy radiator and giving me tips on cauking. Highly recommend if you want a fairly priced job by hghly skilled employees and not subcontractors.
