Top Five Problems From Having Faulty Window Joints

  1. water damage
  2. mold growth
  3. unsightly stains
  4. unwanted bugs and spiders
  5. opens gaps limiting interior temperature control

Importantly, fixing your leaking window frames and joints can relieve all sorts of such problems. We all know how irritating it is to find unwanted pests in our homes. Or having high energy bills due to an air conditioning unit that is always on because of cold air freely flowing through window gaps.  In addition, property managers have to deal with expensive lawsuits from tenants facing hazardous health risks due to mold. 

Common Window Sealing Challenges

Every building substrate material has a different temperature deformation. For example, if your building exterior is stucco the material will expand or compress at a different rate than a building exterior made of glass. Furthermore, a glass building exterior will expand/compress at a different rate than wood. Thus to keep the exterior weatherproof, joints with flexible sealant are required to allow this deformation. It is essential to both use the proper sealant type for each joint type and apply the material correctly. 

The different types of sealants used for window caulking include acrylic, silicone, urethane and hybrid sealants. They all have different strengths and weaknesses.

How To Do Window Caulking Or Window Sealing?

Window caulking, or more accurately window sealing, is a process of replacing or applying sealant on window joints to make them watertight and weatherproofed. There are different types of window joints. Each type of joint requires an appropriate type of sealant to make the area watertight.

Types of window joints: 

  • Glass-to-frame
  • Frame-to-frame
  • Frame-to-wall, etc. 

4 step process: Inspection, Cleaning, Surface Preparation, Application

  1. Inspection: A visual leak inspection is how we begin any caulking service. Many times the visual inspection is conducted at the same time our technicians will perform the caulking service. However, when the leak is not obvious a water test is required to identify the water intrusion area. The water test is exposing various sections of windows to specifically gauged spray water at 5 min per 5LFT rate. Water test shall be done 1-2 days prior to caulking to allow the joints and substrate to dry.
  2. Cleaning: the second step includes cutting off the old caulk. If the old window caulk has cracks or delaminating, it has to be replaced completely. Now we can thoroughly clean the joint from any loose pieces or old sealant.
  3. Surface Preparation: Next is to consider the thickness of the sealant application. A  backers rod should be used on joints deeper than half inch to prevent excessive thickness and unnecessary waste of sealant. If the window sealant is too thick, it has much less flexibility resulting in cracks and failure.
  4. Application: It is now time to caulk window frames. The sealant should be applied and tooled evenly. Tooling is critically important to ensure adhesion and even distribution of window caulk.
