Basements – Frequently Asked Questions

We are committed to ensuring your basement project goes without hassel and if you want to ask us any question that isn’t listed below please get in touch.

Can I just dry line my walls in the basement?

No. Basement conversions require specialist products to control water ingress and dampness. Just dry lining walls can allow the build up of moisture and can lead to outbreaks of Dry Rot. Even though your basement may not be flooded now, it could flood in the future (Source, BS 8102:2009).

What is the CSSW Qualification and what does it mean?

It means Certificated Surveyor in Structural Waterproofing. This is the National Qualification for surveyors in the Structural Waterproofing industry. As this is a very specialist industry, anyone giving you advice on waterproofing your basement should be qualified to do so. If they are not, ask them WHY.

Nowadays most major construction industry organisations (such as NHBC for new-build properties) insist anyone giving advice on basement waterproofing is CSSW qualified.

Will it add value to my property?

Almost certainly. A professionally converted basement has been known to add up to 3 times the cost onto the value of your property (and in some areas of the country, considerably more).

Do I need planning permission?

Unless you want to make external changes (like a new entrance) you probably don’t need planning permission but you probably do need Building Regulations approval. Local Authorities sometimes differ in their exact requirements but don’t worry, we can take care of every aspect of the planning and Building Regulations process, should you require.

Will my basement still be cold and smell when it’s converted?

Absolutely not. A professionally converted basement will remove any damp musty smell and will be like any other room in the house.

Can I view one of your previous projects?

Yes. We have probably carried out a project near to you in the past and many of our previous customers are more than happy to allow you to have a look at the finished job.

What guarantees are available?

As we are approved and qualified basement specialists, the installation of the basement waterproofing system can be covered by a long-term insured guarantee. We operate a waterproofing system guarantee administered by Guarantee Protection Insurance Limited. Please click the link or ask us for further details.

A friend of a friend who is a builder said he can do this work for me?

From our vast experience its highly unlikely a general builder will have the expertise and knowledge to be able to complete the specialist waterproofing without a problem. Waterproofing is one of those areas where ‘a little bit of knowledge can be a dangerous thing!’.

However, its entirely possible you could get your builder friend to complete some ancillary finishing works like plastering or if uncle Bob is a plumber we are happy to work with him to create a fabulous new bathroom in the basement.

Just make sure the waterproofing is carried out by an expert so all the hard work doesn’t get ruined next time the heavens open.
