Questions Before We Build.
Answers Before We Start.

Clear answers to some of the questions clients commonly ask before starting a construction or renovation project.

Every project is different, so pricing depends on the size, specification, materials and complexity of the work. Once we understand the scope, we provide a clear quotation covering the work discussed.

Timescales vary depending on the project. Before work begins, we discuss the expected programme with you so you understand the key stages and likely completion timeframe.

Where approvals are required, we can discuss what your project is likely to need and coordinate with the relevant drawings, consultants and building-control requirements.

It depends on the type and scale of the work. For many projects it is possible, although major renovations may make temporary accommodation more practical during certain stages.

Yes. Northstone Construction is presented as a fully insured contractor, giving clients professional protection throughout the work undertaken on their property.

Start by sending us a few details about your project. We can then discuss what you're looking to achieve and arrange the next step towards preparing a quotation.
