Sealant Replacement

Sealants throughout a buildings exterior facade, including window and door perimeters, control/expansion joints, copings and areas with settlement cracks require maintenance as they deteriorate over time. Ev-Air-Tight LLC has been replacing sealants since 1919, and was the first company in America to use a pneumatic caulking gun for which it held a patent. We pride ourselves on proper removal, preparation and installation of appropriate sealants based on your application.

Replacing sealants as they deteriorate over time can be an important part of any building’s regular maintenance routine, especially given the critical nature of sealants in the first place. Any sealant is generally applied for the purpose of protecting the substrate underneath, and to extend the life of that layer of material. Since building materials are becoming more costly all the time, the protection afforded by a good sealant is more important than ever. Sealants are generally chosen for their ability to adhere to a given surface, as well as for their ability to provide protection for the valuable surfaces underneath.

Seal Up your Buildings Exterior Facade for Maximum Protection

At Ev-Air-Tight LLC, we have been in the business of applying sealants to surfaces for more than 100 years now, and it’s safe to say that we have it down to a science at this point. In fact, we have even been the industry leader in this country, developing the first patent for an efficient pneumatic caulking gun which could be used to effectively apply sealants to building surfaces. As our specialists are well aware, there are all kinds of surfaces which require sealant application, and all of them require superior protection against weathering and normal wear and tear.

For instance, window and door perimeters require sealing so that there is no leakage around the frames, which could lead to further damage in the interior. Control and expansion joints need sealants to be applied, as do copings and areas which have sustained cracks due to settling processes. Over a period of time, all these areas will undergo some degree of deterioration, and this can be prevented in large part by applying the right type of sealant to the area.

Proper Sealant Application to Prolong your Exterior Surface

It isn’t just having the expertise to properly apply a sealant that will help to prolong the life of any surface being treated – it’s the knowledge of which particular type of sealant should be used. There are silicone-based sealants, urethane-based sealants, acrylic sealants, and polysulphide sealants, to name a few. Knowing which of these is most effective on a given type of surface, and in specific climatic conditions can make all the difference between success and failure for that sealant, over a period of years.

Polysulphide sealants for example, are very good in cold-weather applications and will retain their powerful sealant characteristics, even under fairly extreme conditions. It’s also necessary to have a good understanding of how large a joint can be serviced effectively by a sealant, what its resistance level is to moisture or chemical presence, and what its setting and cure time will be after application. When you have your sealants replaced by our trained specialists, you can be sure that they will bring all the necessary knowledge and experience to the task, so you can benefit by having the best possible results.
