1. Caulk for Air Sealing
Air sealing your home with caulk is one of the most affordable and effective ways to upgrade insulation without invasive, costly, or complicated procedures.
This application can decrease the number of air leaks in your home and improve its ability to maintain steady temperatures as the seasons change. Additionally, it helps keep water runoff and bugs at bay.
The best caulk types for air sealing include latex, expandable foam, and butyl rubber.
Latex caulk is one of the most common caulk selections for household DIY projects.
We recommend the DAP Alex Painter’s Acrylic Latex Caulk because it dries fast and lasts long. This product fully dries within two hours and can stay intact for 10-15 years. You can use it to fill gaps between doors, drywall, and windows.
- DAP ALEX PLUS All Purpose Acrylic Latex Caulk Plus Silicone is an excellent quality, all purpose caulk for sealing a wide variety of interior and exterior surfaces. It contains silicone additives for greater flexibility and adhesion, and shrinks less for a durable, 100% waterproof seal.
- ALEX PLUS is paintable in just 30 minutes with latex or oil-based paints, saving time. It will not shine through or discolor paint finish for superior paint results.
- Easy to apply and tool, low in odor and cleans up easily with water. Cured caulk is mold and mildew resistant.
Silicone is a bit more flexible and good for areas around windows, doors, the bathroom, kitchen, or anywhere that needs a bit more protection.
The most popular silicone caulk you can get on Amazon is the Gorilla 100% Silicone Caulk Sealant. It’s also paintable within 30 minutes of drying.
- SEALS OUT WATER, AIR & MOISTURE
- 30 MINUTE WATER READY
- INDOOR/OUTDOOR: All Weather
- 100% WATERPROOF - MOLD & MILDEW RESISTANT
- WON’T YELLOW, SHRINK OR CRACK
Caulk doesn’t have to be an exclusively indoor material. Certain types of caulk are great for exterior settings too.
For example, butyl rubber caulk is an excellent choice for your outdoor sealing projects. You can use it to seal up metal, mortar, aluminum, concrete, rubber, and other outdoor materials.
There is hardly a better choice for butyl rubber caulk than the Flex Shot Rubber Adhesive Sealant Caulk. This product will help you cover small holes that cause air leaks in your home.
- Caulks, bonds and seals virtually everything!
- No need for a caulking gun! The free extension tube makes even hard-to-reach repairs easy
- Gives you a perfect bead, every time. No running, no dripping, no mess
- Expands and contracts to fill in huge cracks and holes
- No waste – use it again and again
2. Can Spray Foam Insulation
Spray foam insulation is handy for sealing walls, ceiling cavities, and floors. You can use this spray foam in almost every section of your house, and it never loses its shape.
What sets spray foam apart from the caulk products we discussed earlier is its superior ability to maintain a consistent temperature in your home, which helps lower energy bills.
It does this by preventing air leakage. As a result, your air conditioner and furnace will be more effective and have to run for less time, thus reducing your monthly energy bills.
Additionally, spray foam insulation can help reduce condensation levels in your home. Condensation happens when the outside temperature comes into contact with the air inside your home, and poor insulation is the most common culprit because it can cause air leakage.
Luckily, spray foam insulation is an easy solution.
We recommend Loctite TITE Foam to remedy condensation and air leaks. This spray foam helps prevent leakage from both inside and outdoor air and is the most popular spray foam product on Amazon.
- Expands To Fill: Loctite Tite Foam Gaps & Cracks fills, seals, and insulates effectively around gaps and cracks up to 1 inch in size
- Premium Durability: Polymer foam based on purified and concentrated ingredients withstands harsh UV rays for long-lasting results
- High Density Foam: Offers high density with a uniform cell structure for durability and overall insulation for your remodeling needs
- Superior Flexibility: Withstands building and material movement without compromising its seal
- Strong Adhesion: Sealant bonds to most building materials like wood, concrete, brick, stone, metal, pvc, and more
3. Electrical Outlet Gasket
Buying and installing an electrical outlet gasket is an affordable and accessible home improvement that can save you energy.
Sometimes, you may feel cold air coming from your switch plates and outlet sockets on a windy day. Things might be worse during the winter. However, this can be easily fixed by installing electrical outlet gaskets.
We recommend these Duck Socket Sealers because they help insulate all the wall cavities behind switch plates and outlets, creating a barrier that prevents outside air from getting inside.
- Socket sealers help improve energy efficiency
- Flame retardant
- Easy to install
- Comes with 16 outlet sealers, 6 switch plate sealers and 2 decorative GFI switch plate covers
- Increase comfort and eliminate drafts in your home
When making your purchase, it’s crucial to ensure you buy a gasket that matches your outlet design.
4. Weatherstrip Adhesive
Weatherstrip adhesive is another air sealing tool that makes it easy to make simple yet effective home improvements.
It gives you a waterproof seal that resists vibration, heat, detergents, temperature changes, and oils.
This adhesive can permanently bond various surfaces, including metal, vinyl, rubber, and fabric. It works best for sunroofs, trunks, car doors, and more.
Weatherstrip adhesive cures quickly and is easy to use, even for beginners. All you have to do is squeeze it directly from the tube to the surface. Then, use a small brush to spread it on each section and allow the adhesive to cure for about 24 hours.
5. Ductwork Insulation
Ductwork is simply a system of pipes and ducts circulating cooled or heated air throughout your house. Installing duct insulation poses many benefits, including lowered energy consumption, reduced utility bills, and creating a more comfortable home.
Insulation is a great way to prevent air leakage inside your home’s ductwork system. A good ductwork insulation level not only prevents energy wastage and leaks but also minimizes condensation buildup and temperature drops.
These insulation materials come with different R-values. HVAC experts recommend that you go for the one with an R-value of at least five. Even so, eight is the most preferable and the highest R-value.
When buying, go for the duct wrap, like Reflectix. It is the newest and most effective ductwork insulation available. Fiberglass also does well, though it has a few concerns with moisture absorption.
Amazon has some duct insulation in different sizes that you can buy in packages. Here are the top 5 bestselling insulation products you can purchase:

Cellulose is another must-try home insulation tool. This material mainly comes from recycled newspapers, and can be used in both old and new homes.
It’s a great weekend DIY project for most experienced homeowners. You can rent the machine required to blow cellulose insulation into an attic at a local home improvement store.
You may decide to go for dense-pack cellulose or wet-applied spray cellulose. The dense pack adds thermal insulation into wall cavities while acting as a soundproof material.
Wet-applied spray cellulose also has the same sound and thermal properties, though it is best suited for new houses before setting up the drywall.
The best part is that cellulose is very affordable and works better than most other insulation materials. However, the exact amount you will incur varies, depending on labor, size, and supply cost.
In addition, the boric acid and aluminum sulfate in cellulose create resistance to pests, mold, and fire.
We recommend US Greenfiber Cellulose because it’s inexpensive and made of recycled materials.
You’ll probably want to pick these up locally due to the shipping costs. And if you buy enough, they should be able to give you the blower machine as a free rental! Make sure to ask the store about this before spending more money on the machine.
8. Fiberglass Insulation
Fiberglass is one of the most commonly used insulation materials. Most people prefer it for DIY projects because of its capability to reduce heat transfer. You can also find it in duct insulation and rigid boards.
This insulation comes in different types, including rolls, batts, and loose-fill. Its design enables it to slow the spread of cold, heat, and sound in structures. In addition, it traps air pockets, which helps maintain appropriate seasonal temperatures.
Fiberglass is generally inexpensive and best suited for standard joist and stud spacing, free from obstructions.
We recommend Home Depot or Lowes for a local pickup again because of how bulky the packaging is. This would lead to really expensive shipping costs if ordered online. They are usually readily available and in stock as well.
9. Mastic Sealant
For durable bonds and connections, mastic adhesive has your back. You can use this sealant for DIY projects on nearly all surfaces, including glass, steel, timber, marble, and various boards.
It also serves as the best joint-sealer for doors and windows and stands out as one of the best thermal insulation coatings on pipes and ducts.

10. Backer Rods
Backer rods are flexible foam pieces that serve as backings in cracks and joints to control the amount of caulk or sealant used. This DIY project tool comes in various types, sizes, and lengths for optimal fitting to the joint or crack size.
Here are some benefits of using backer rods:
- Minimized caulk or sealant consumption by reducing sealant depth.
- Boosted elasticity in the joint sealant.
- Forcing the adhesive close to the joints’ sides for a superior bond.
- Creating a bond-breaker, making it easy to clean the joints and refill them as required over time.
Backer rods come in three distinct types: closed-cell, open-cell, and bi-cellular. Each one has its features and specific uses.
Closed-cell backer rods are best for expansion joints, curtain wall joints, and partitions. Open-cell backer rods better serve window glazing, parking decks, contraction, and expansion joints. Finally, bi-cellular backer rods work well in irregular joint applications.
Their prices also vary, depending on the features. But this M-D Building Backer Rod is cost-effective and functional.
