Builder Dispute in Quality of Work

Seeking a solicitor versed in Scottish construction law to advise on and manage a dispute with a builder. Contracted for gas, electrical and plaster boarding works, the job remains incomplete and substantially delayed. The builder has failed to provide required receipts and statutory sign‑off certificates stipulated in the contract. I require legal guidance on remedies and a solicitor to correspond with the builder, assert contractual obligations, and pursue appropriate resolution or enforcement.
