Does the Old Siding Need to Come Off?
This depends on the siding already on your house and its condition. In many cases, vinyl and aluminum siding must be removed prior to installation.
When possible, such as when a home has solid wood siding in good condition, contractors can install lath strips over the existing siding and install the new siding on top. This saves a lot of money because you avoid the cost of tearing off and disposing of the old material.
Do You Have to Buy House Wrap?
Yes, house wrap is a standard purchase for siding replacement. Even if your home has house wrap (and most older homes do not), old house wrap should not be reused due to nailing holes from the previous siding.
Adding a proper Weather Resistive Barrier, or WRB, during a siding project is a smart move. Here is what it typically costs:
| Underlayment Option | Price Range | R-Value |
| Standard House Wrap | $2,000-$3,000 | Zero, but drastically reduces air penetration and heating costs |
| Reflective Foil House Wrap | $2,000-$3,000 | R1-R3 |
| 1 Inch of Foiled-Faced Foam | $6,000-$15,000 | R6 |
Current building codes require walls to have R21 insulation for new construction. Most older homes have R13 or less. Adding foam board during a siding job can make a real difference in your heating and cooling bills.
Should You Update Soffit and Fascia at the Same Time?
If your soffit and fascia are stained, damaged, or pulling away from the house, now is the time to address them. Placing new siding next to old trim can really draw attention to how worn out the soffit and fascia have become. Homeowners who skip upgrading their trim often don’t like how it looks once it has to stand up against the new siding.
It is almost always cheaper to have soffit and fascia replaced as part of a larger project rather than as its own job. Bundling the work together saves on setup time and labor costs.
What Should You Expect During a Siding Estimate?
During a siding estimate, you can expect your Estimating and Design Consultant to:
- Walk around the entire house and photograph all sides.
- Document all penetrations, including outlets, lights, and doors.
- Check your window and trim needs, soffit and fascia condition, and look for signs of damage or rot.
- Verify whether you have house wrap in place.
If you are willing to wait, you may be able to get a 3D rendering of your home, so long as your contractor offers this service. This lets you see what different colors and styles will look like before you commit to anything.
Can You Install Siding Yourself?
If you are mechanically inclined and willing to put in the work, you can certainly install your own siding. But there are some tricky parts of installation that DIY homeowners should be aware of.
Siding expands and contracts with temperature changes. If you install siding too tightly together, the siding may wave and buckle in high temperatures as it attempts to expand.
There are specific requirements for how far apart seams can be, how close siding can sit to windows and door jams, and how tight to nail it. You want the nails tight enough that the siding will not blow off, but loose enough that it can still move and slide as it expands. Getting this wrong leads to buckling, cracking, and other problems down the road.
What Questions Should You Ask Your Siding Contractor?
Before you hire anyone, make sure you get clear answers to these questions:
- Is there a price difference between colors?
- Does the siding have foam backing built in?
- Will you install house wrap? Will you wrap my windows and doors?
- If there is foam board, will you tape the seams properly?
- Will you reuse the existing window trim or replace it?
- Do you remove exterior lights and put them back on, or is that my responsibility?
- How long will the project take?
Most siding jobs take around 10 days to complete, though this can vary depending on crew availability and the complexity of the job.
When Should You Replace Your Siding?
Unless there is visible damage, replacing siding is mostly a matter of personal preference. A lot of homeowners buy new siding because they want to change the look of their home, not because they absolutely need it.
That said, it is rare to see a house that needs siding replacement without finding at least some damage behind the old material. Lawn mowers kick up rocks, the weather takes its toll, and small issues can turn into bigger ones over time. If your siding has seen better days, it might be worth getting an inspection to see what is going on underneath.
What Happens Next?
Siding costs vary dramatically. The same house can get quotes ranging from $18,000 to $70,000, depending on the material, color, and extras involved.
The best thing you can do is have a budget in mind before you meet with a contractor. Knowing the max amount you’re willing to spend helps to narrow down your options and avoid choice anxiety.
