About Us

Welcome to the Celtic Renovation Services website. We are a Florida-State-licensed, General Contracting firm, owned and operated by Ronald L. McDonald.

We have been known widely for our exemplary work as HUD 203K construction specialists doing complete remodels and home additions for many decades throughout Florida.

We have been approved for and have worked with numerous lenders: Bank of America, Regions Bank, Wells Fargo Bank, TD Bank, Real Estate Mortgage Network (REMN), Sun Trust Bank, Sun West Bank and Michigan Mutual, just to name a few.


Our experience in budget remodeling has also given us a strong reputation with Real Estate Investors, Fix-Uppers, Flippers and budget-minded property owners.

Celtic (a Scottish/American-owned Company) prides itself in its new construction division, working with well-established modular home manufacturers building new homes in Central Florida.

We also have extensive experience in disaster property preservation and repair, and have done extensive work with Citizens Insurance, State Farm Insurance, Tower Insurance and others, for sink holes, floods and natural disasters.

With over 50 years of construction and real estate experience, Ronald McDonald has operated as a real estate investor as well. This gives the company an unique understanding of building to create real value in real estate while understanding the importance of not over-improving a property to the detriment of the owners.

Celtic Renovation Services is a licensed, insured general contractor (#CGC059859) and Central Florida’s premiere remodeling company for homes and small businesses, focusing on disability upgrades and all forms of construction, including sink hole repair.
