basement renovation elements to consider...

When considering a basement conversion you need plenty of prior planning and enough research to discover how best to proceed with the project.

Moisture:

If you live in an older home, your basement was built for cool storage and lacks an appropriate drainage system and exterior waterproofing. In this case, you may need the services of a professional excavation contractor to achieve and maintain dryness in the space.

Access / Safety:

Make sure stairway access either inside or outside is compliant with current building codes, dependent on how you renovate the basement space. Also make sure adequate headroom and legal egress exists, and a functional smoke detector is installed.

Plumbing:

What purpose you intend to use the basement space for will determine if plumbing is necessary. If you decide on a bedroom with an attached bathroom or a washing machine, then of course a plumbing setup will be necessary.

Lighting:

Often one of the challenges with basement renovations is getting natural light into the space. The use of atriums, light tunnels and strategically placed windows can help to overcome these challenges a good lighting plan is a critical part of a successful basement renovation.

Electrical:

An older home’s electrical system is dated and will need to be brought up to code. Don’t stint on this expense because safety first should be your priority for family or anyone else using the space.
