Since its founding in 1935, Twi-Laq has been owned and operated by the Wels family. In 2006, Twi-Laq relocated its entire operation to the Hunts Point region of the Bronx, where a new, modern manufacturing and distribution facility was constructed. Today, Twi-Laq remains uniquely positioned in the distribution marketplace as one of the very few manufacturers that sell direct to its customer base, which includes Building Service Contractors, Healthcare and Educational Facilities, Real Estate Management companies, and the Hospitality Industry on an international scale.

Product Selection

 Over the last 75 years, we have established solid relationships with all of our vendors; it is one of the keys to our success in today’s marketplace. Our suppliers understand our needs and the often unique requirements of our customers. Looking for something special? Chances are, one of the Wels has seen it, used it, heard about it, and knows where to get it. It’s one of the things that make us special. Need us to stock a specific product for you? Need just one case? No problem. The variety of chemicals and products that we offer is rivaled by few. It’s what we do to meet the demands of our customers.

Our chemical line encompasses more than 75 years of contractor tested and tried formulations. As a manufacturer, our relationships with polymer and detergent manufacturers puts us in a unique position to quickly evaluate and introduce innovative, cost and labor saving products long before our competition even knows the technology exists. And you, our customer, are routinely involved in the evaluation of new products as we continue to develop the newest cleaning technologies that create safer and healthier building interiors and a more sustainable environment. Green Cleaning Since 1995, Twi-Laq has been at the forefront of the Green Cleaning movement. Over the last fifteen years, green cleaning products has achieved the highest and most consistent growth of any of our product lines. We are incredibly well positioned to help our customers implement their Green Cleaning initiatives.

Twi-Laq manufactures its own branded line of Green Seal, Ecologo and EPA’s DFE certified floor care products. We work to understand your needs as it relates to Green Cleaning and create a strategically tailored program help you implement your company specific Green Cleaning initiatives on any and every level. 40% of the points required for LEED-EB certification can be achieved through the implementation of a Green Cleaning program. Twi-Laq will work with you through a series of on-site inspections to identify areas of concern and the corrective measures required to achieve points towards certification. Twi-Laq has helped countless BSC’s, hospitals, educational facilities, and management companies implement their green cleaning initiatives through our extensive product offerings and site specific training and educational programs.

Quality Control

Twi-Laq boasts a warehouse and manufacturing crew with an average employment of over 15 years. Over the years, as raw materials have developed, our raw material suppliers continuously work with our manufacturing personnel refining our various manufacturing process to ensure the performance of our products can be repeated with every batch. We stock all of our most popular floor finishes, strippers and cleaners. Specialty and custom blended chemicals are made as needed in controlled batches and shipped out as ordered. Twi-Laq performs a variety of in-house lab tests to ensure each product’s efficacy before a single gallon ever gets filled. Our suppliers, many of whom help in the formulation of our finished goods, function as an additional level of quality control. We consistently send out our finished goods for more thorough testing to ensure the final product always meets all formulation and performance standards. For our customers, Twi-Laq utilizes Underwriters Laboratories (UL) for listing its most popular floor care products as to slip resistance, a process that some of our competitors deem too costly and unnecessary. We feel that it's your guarantee of true safety and quality. Underwriters Laboratory comes into our plant several times a year, unannounced, to draw samples of our floor finish for testing. Since our inception, we have maintained a perfect record with UL inspectors, the DEP, OSHA, and the EPA. UL listing is an additional assurance of quality of the products we manufacture. Distributors can have any manufacturer put their labels on any product. There is no guarantee that you are getting the same product from one month to the next, never mind a product from the same manufacturer. With Twi-Laq and Sun-Glo you get consistency, the same product you received last month, and the same one you will receive next time, every time, you place your with us; with the same quality control and technical support.


The key to success for the implementation of any cleaning program is training. As the manufacturer, there is no one more familiar with the proper use of our chemicals that the trainers that make up our implementation and training teams. Twi-Laq routinely conducts on-site training seminars on numerous subjects such as proper floor care, carpet care, stone care and restroom cleaning. During these classes we cover the chemical make-up, proper product use/dilution, and safety/MSDS training. When working with Green Products, we stress the positive effect that the use of these products, specifically the EnviroCare line of products, mean to the individual cleaner’s health and well being. Additionally, Twi-Laq conducts safety training for all the products we sell, regardless of the manufacturer. As part of our contract with Marriott, we have conducted stone care training seminars in the UK, Europe, the Middle East, Central and South America and are available to conduct (or arrange) for training seminars in any region across the country on virtually any topic. Our numerous vendors make themselves available, where they too will conduct on-site product or equipment training seminars. There are also numerous training and certification schools offered by many of our manufacturer partners. We can arrange attendance at many of these schools/classes for your corporate personnel, many which carry industry certifications.


Twi-Laq delivers to our customers’ locations throughout New York City, Long Island, Westchester, New Jersey, and Connecticut via our corporate run trucks. Our 24-48 hour delivery window ensures that your orders arrive when they’re needed the most…right away. For locations outside of our direct delivery area, shipments are made via common carriers. 


In 2006, coinciding with its move to the Bronx, Twi-Laq implemented a new industry specialized computer system. In addition to having EDI and online ordering capabilities, the system was chosen for its extensive reporting capabilities.

Twi-Laq maintains the ability to analyze virtually every aspect of your purchases; from location specific orders down to which location purchased a specific product, to the impact of price changes. With Twi-Laq you’ll have the ability to manage your purchases on a global basis whether orders are generated at the corporate or site level.



Twi-Laq works through a system of contract pricing for virtually all the items we supply to our customers. We work with you to monitor your purchases so that we may recommend alternatives that promote increased production and savings. We work with both you and our suppliers to negotiate specific contracts based on your specific needs, many of which can be implemented nationwide. Pricing will always be fair and competitive and represents the effect of a highly competitive New York Metropolitan market.

Since Twi-Laq manufactures and sells direct, you see the benefits of dealing with the manufacturer in our formulations. Each and every formula is created with performance in mind, not price. This is evidenced in the highest dilution ratios for our cleaners and strippers and in the quality of our floor finishes. We know what you need, because we work with you in the field, not in a lab; we understand what you want, because we listen.
