What sets Celmark’s construction

services apart from the rest is that we understand an owner’s needs. We have a deep understanding of the development process, where controlling costs and managing delivery times are paramount. Our team of professional construction experts has an impeccable and proven record of satisfaction with developers, real estate professionals and investors.

We encourage our clients to engage us early in the design process, so we can assist the entire development team in providing robust project budgets, offer creative and effective design solutions to meet budgets, provide assistance with local permitting jurisdictions and prepare realistic timelines for effective and timely delivery of the project. Often, depending on the complexity of the project, Celmark will provide these pre-construction services at no cost to our clients because we want to earn your business.


Celmark as the General Contractor for our project performed an excellent job not only from the beginning till the end, but was very responsive in taking care of any follow up issues after the completion. Tyler Slane and Tim Van Heyningen were always available and I thoroughly enjoyed working with them
