How do I arrange for you to provide a quote?

What forms of payment do you accept?

We accept payments in the form of cash, cheque and BACS transfer. Payments can be divided into separate installments if needed to give you piece of mind.

Do you take waste materials away after the job is complete?

Yes. We never leave waste materials on your property. All work is finished to the highest standards but sometimes a skip is necessary on site to store the waste. This will be discussed prior to the skip arrival on your property (if needed).

How long do your quotes last for?

Our quotes last for 60 days, but rarely do the prices fluctuate rapidly so you can be safe that re-quoted prices will often be similar if not the same price. We will try to honor our quotes as best as we can.

When do I pay for the job?

We ask that we receive part payment for the job upfront to secure our services. When the job is completed, we would require the remaining amount be paid. In some cases we can split larger jobs into individual payments that can be paid as key stages of the job are completed. We work with you to manage this.

If I receive a cheaper quote, will you beat it?

We will try our best to be as competitive as possible, but we cannot guarantee to beat quotes from other companies. Often, cheaper ‘cowboy’ builders can cause more damage which could cost you dearly to put right. We’ve been in business for over 30 years and provide a quality service for an affordable price. We pride ourselves on working with our customers to exceeded their expectations.

Do you offer a warranty or guarantee on your work?

Yes. We offer a no-quibble guarantee for any faults, leaks, or other unforeseen issues with any of our building work, provided we are notified within 6 months of the completion. Provided any issues are a result of our services and not excessive force/vandalism/other we will fix any issues you’re experiencing free-of-charge to put your mind at rest. We are proud of our work and will always help any customers experiencing problems. Over time buildings been maintenance and so it is inevitable that you will need to address certain issues every few years or so.

Do you undertake larger commercial jobs?

Yes – Provided we feel we have the availability to take on the job. We undertake both commercial and domestic construction work for larger and smaller jobs, from building a garden wall to a new home extension and lots in between.

Who manages the builders, inspects the quality of work etc?

We have a solid management structure in place where we plan and execute individual tasks sequentially. No procedures are skipped. At each stage of the build we evaluate the job and check for quality before we proceed to the next stage. We are confident that we effectively manage our time and the builders skills.
