Did you know
Did you know there are two kinds of sealers?
Water-Based Sealer
Water-based asphalt sealer is a protective coating applied to asphalt surfaces to extend their lifespan and enhance their appearance. It forms a barrier against damaging elements like UV rays, rain, oil, and everyday wear, helping to prevent cracking and fading over time. Unlike solvent-based alternatives, water-based formulas are lower in VOCs, making them a more environmentally friendly option that is safer to apply in residential and commercial settings.
Oil-Based Sealer
Oil-based asphalt sealer is a heavy-duty protective coating known for its deep penetration and long-lasting durability. It bonds directly into the asphalt surface, providing superior protection against harsh weather conditions, heavy traffic, and chemical spills like gas and oil. While it tends to have a longer cure time and higher VOC content than water-based options, many contractors prefer it for its exceptional strength and ability to restore and rejuvenate heavily worn or oxidized pavement.

Our Reviews Tell The Story


Alexander Asphalt did an outstanding job on my driveway. The project was more complicated than a typical paving job, but their team handled it professionally from start to finish. The pricing was very fair, the work was completed quickly, and the quality exceeded my expectations. Additionally, David's communication was excellent throughout the process, and the finished product looks fantastic. I highly recommend Alexander Asphalt to anyone looking for high-quality paving work at a reasonable price.
Alexander Asphalt had done my daughter’s driveway and I was very impressed with the outcome. I got the phone number from her and immediately was impressed with their prompt reply. Their estimate was a fair price and was fully explained. They showed up promptly to do the work as scheduled. Their crew was efficient and their work was excellent++. Both Eric and Dave were always there to help out and ensure job was done perfectly. I will gladly recommend them for their work ethic and superior workmanship. Thank you for a great job. Second job done by Alexander Asphalt. A year ago I had my driveway redone (see above). I recently had them seal my driveway. As usual, the workers did a great job. I was completely satisfied and pleased with their work ethic. I would recommend them again to anyone who wants a perfect job. Thanks for your outstanding work.
We have a very long driveway and the job they did was exceptional. Very easy to deal with, very professional, excellent clean-up and the driveway that has some serious deterioration now looks beautiful again. Thank you Erik, Dave and crew!
I prefer to do my own maintenance and other construction work as I am a perfectionist and quite good at what I do, but laying asphalt isn’t one of my skills, nor do I hv the equipment (under stated) So when I choose a contractor, he must meet my standards! Not only did David and Erik meet, they surpassed my expectations and standards! Made me feel involved and that my choices and preferences matter! Plus they are extremely nice people and rather reliable!! Always on time! They work right along side their crew and ensure the right quality! I’m quite pleased w my new driveway, of over 400 feet and some, but most of all, I know I experienced fare, honest and exceptional service(s). I insisted David put me on his auto maintenance schedule for future sealing and I know I won’t hv to worry about it getting done and done right! Zero risk hitting these two!! Thank you guys! Vinny
Of the 3 estimates I received for having my driveway resurfaced, Alexander Asphalt was not the cheapest but "in the middle" of the 3. I chose them because Eric, who provided me with the estimate, arrived on time and presented himself professionally. He understood exactly what I wanted done, and was quick to provide me with the estimate and was able to put me on the schedule for the install. Alexander Asphalt did a FABULOUS job! The crew worked hard and diligently. Shortly after completion, my neighbor texted me and said the drive looked great! We thought so too. I highly recommend them.
I can’t put in to words how happy I am with not only the driveway, but the company’s communication. I came home after working all day to a driveway I could not even dream of, it looks amazing! They also communicated with us from start to finish. We were aware of when it was being done and how long it would take. I highly suggest using Alexander Asphalt! We will be using them for sealcoating in the future!
Would highly recommend. They redid my asphault drive efficiently and at an extremely reasonable price.
Our experience with David and the crew is nothing short of positive. They provided a fair quote, came on the day scheduled, and completed the work to our mutual satisfaction. They were great at communicating and receptive to small changes in the job. Highly recomend.
