Door and window weatherstripping seals the gaps around doors and windows with new weatherstripping, door sweeps, threshold seals and caulk, so cold air stays out and warm air stays in. Csiszer Property Maintenance, an insured handyman company serving Essex County and Union County, NJ, does it for homeowners, landlords and businesses, from one drafty entry to every window in the house. The best time is fall, before heating season starts.
What Is Door and Window Weatherstripping?
Weatherstripping is a flexible seal on the parts of a door or window that move, while caulk seals the joints that don't. Both are part of our door and window repair services, and most homes need a mix of the two.
According to the U.S. Department of Energy, weatherstripping is for moving components such as doors and operable windows, and caulk is for cracks and gaps between stationary parts, like the joint where a window frame meets the siding. Using the wrong one is the most common reason a draft comes back, or a window gets sealed shut.
Older Essex County homes add their own leaks: wood sashes that have shrunk over the years, doors that have settled out of line, and caulk that has dried and cracked through many winters. A draft check finds where the air is actually getting in, so each gap gets the seal that fits it. [PREENCHER: se a Csiszer faz isolamento de sótão ou parede]
Door weatherstripping
Worn or flattened seals along door jambs replaced so the door closes against them.
Door sweep installation
New sweeps set at the bottom of the door to meet the threshold without dragging.
Threshold seals
Worn threshold inserts and bottom seals replaced where light shows under the door.
Window weatherstripping
Seals fitted to sash edges and meeting rails, chosen so the window still opens.
Window caulking
Cracked caulk at frames and trim cut out and replaced on stationary joints only.
Draft check
Each door and window checked for leaks, so the fix targets where the air gets in.
When You Need Weatherstripping: 6 Signs
You need weatherstripping when you can see, feel or hear air coming around a closed door or window. These are the six signs we see most.
Light shows under the door
Daylight at the bottom or sides of a closed door means an open path for cold air and bugs.
A sheet of paper slides out
Close the door or window on a sheet of paper. If it pulls out easily, the seal is worn or flattened.
Curtains move on windy days
Moving curtains or blinds with the window shut point to air leaking around the sash or frame.
You hear a whistle in the wind
A whistle or rattle during a storm is air forcing its way through a gap that's too narrow to see.
Caulk is cracked or pulling away
Old caulk shrinks and splits. Gaps along the frame let in air and, on the outside, water too.
The sweep is torn or missing
A door sweep that's ripped, stiff or gone leaves a gap you can often feel with your hand.
How Our Weatherstripping Works, Step by Step
Our door and window weatherstripping takes five steps: photos or a description, a review, a written quote, the sealing itself, and a final draft check with cleanup.
-
Send photos and your town
Photograph the gaps around each drafty door and window and any light showing under the door, and say which rooms feel coldest.
-
We review, or visit if needed
We check whether each gap needs weatherstripping, a sweep or caulk, and whether a door or sash needs adjusting first. If photos aren't enough, we visit first, at no charge, then send the written quote.
-
Get a written quote and pick a day
You get a written quote before anything is booked. Approve it and choose a weekday between 8 AM and 5 PM.
-
Remove old seals and fit new ones
Worn seals and cracked caulk are removed, surfaces are cleaned and dried, and new weatherstripping, sweeps and caulk go in.
-
Check for drafts and clean up
Each door and window is closed and checked again, sweeps are adjusted so they don't drag, and the area is cleaned before we leave.
What's Included in Door and Window Weatherstripping
Every weatherstripping job includes the draft check, new seals, sweeps and caulk, and cleanup. The only things left out are jobs reserved for a licensed pro.
Included
- Door weatherstripping
- Door sweeps and threshold seals
- Window weatherstripping and caulking
- Draft check and cleanup
Not included: needs a licensed pro
- Old caulk or glazing that tests positive for asbestos: a licensed abatement contractor
- Checking gas furnace or water heater venting: a licensed HVAC contractor
- Moving outlets or switches on outside walls: a licensed electrician
The EPA notes that some window caulk and glazing compound can contain asbestos, and the Department of Energy's guide to air sealing warns about combustion appliance backdrafts in tighter homes.
How Much Does Door and Window Weatherstripping Cost?
Weatherstripping cost depends on the number of doors and windows, the type of seal and the condition of what's there now. Photos help us review the job, and the price is in writing before anything is scheduled.
Most weatherstripping is priced by the job, so the quote covers the draft check, removing old seals and caulk, the new materials and cleanup. A door sweep on a well-aligned door is quick; a door that has sagged, or old wood sashes with worn channels, take more fitting before a seal will work.
Sealing the whole house in one visit is the most efficient way to do it, and fall is the season to book it. Landlords can group every unit in a building into one quote before the heat goes on.
| Factor | How it affects the price | Example |
|---|---|---|
| Number of doors and windows | More openings take more material and time, but share one trip | One entry door vs. a whole floor |
| Seal type | Sweeps, jamb seals, threshold inserts and sash seals each cost and fit differently | A stick-on sweep vs. a new threshold seal |
| Condition of old seals and caulk | Hardened caulk and glued-on seals take longer to remove cleanly | Fresh caulk vs. layers of old caulk |
| Door and sash alignment | A sagging door or loose sash needs adjusting before a seal can work | A square door vs. a settled one |
| Access | Upper-floor exterior caulking and blocked windows add setup time | A ground-floor frame vs. a second-floor one |
| Other jobs in the same visit | Grouping small jobs gets more done for one trip | Weatherstripping plus a window repair |

Weatherstripping Mistakes That Let the Draft Back In
Most drafts come back because the wrong seal went on the wrong gap, or it went on in the wrong weather. Here's what to avoid, how to choose caulk or weatherstripping, and how to get ready.
Six Common Weatherstripping Mistakes
Six mistakes cause most weatherstripping that fails: caulking a joint that moves, caulking in cold or damp weather, new caulk over old caulk, foam tape where there's friction, sealing a crooked door and a sweep set too low.
Caulking a joint that moves
Caulk on a sliding sash or door edge seals it shut or cracks in days. Moving parts get weatherstripping.
Caulking in cold, damp weather
The Department of Energy advises caulking in dry weather above 45°F, so it can set and bond properly.
New caulk over old caulk
Fresh caulk laid over cracked caulk pulls away with it. Old caulk has to come out first.
Foam tape where there's friction
Soft foam on a jamb that the door rubs tears fast. The seal has to suit the wear it gets.
Sealing a crooked door
On a sagging door, a seal touches at one corner and gaps at the other. The door is aligned first.
A sweep set too low
A sweep that drags on the floor or a rug wears out and makes the door hard to close.
Caulk or Weatherstrip: How to Decide
Use caulk on cracks under a quarter inch between parts that don't move; weatherstrip anything that opens. If a door drags or a sash falls, start with our door repair service or window repair service.
Use caulk when
- The joint never moves, like frame to siding
- The gap is under about a quarter inch
- The weather is dry and above 45°F
- Old caulk has been removed first
Use weatherstripping when
- The part opens, like a door or sash
- Light shows under or around a door
- The gap changes with the seasons
- A seal has to take rubbing and wear
Before Your Weatherstripping Visit: A Quick Checklist
Six small things make the visit faster. If a door sticks only in humid months, read door sticking in summer first, since swelling changes how it seals.
- Do the paper test on each door and window
- Photograph any light showing under the door
- Note the rooms that feel coldest on windy days
- Tell us if the window caulk or glazing looks original
- Mention a gas furnace, boiler or water heater
- Clear a few feet in front of each door and window

Weatherstripping Questions, Answered Straight
These are the questions people ask most before sealing doors and windows. For other jobs, see all our door and window services.
How much does door and window weatherstripping cost in New Jersey?
It depends on the number of doors and windows, the type of seal each one needs and the condition of what's there now. Send photos of the gaps and any light under the door, or describe the drafts. If the photos show enough, you get a written quote; if the drafts need a closer look, we visit first, at no charge. Either way, the price is in writing before anything is scheduled.
Will weatherstripping lower my heating bill?
It cuts drafts, which is the part you feel. How much you save depends on the house, its insulation and how leaky it was, so we don't promise a number.
When is the best time to weatherstrip in NJ?
In the fall, before heating season. The U.S. Department of Energy recommends caulking in dry weather above 45°F and applying weatherstripping to clean, dry surfaces above 20°F, which makes early fall in New Jersey the easiest window.
Can I weatherstrip my own doors and windows?
Simple seals can be DIY, like a stick-on door sweep or foam tape on a window that doesn't open. Our guide How to Fix Drafty Windows walks through the tests. Doors that are out of line or old sashes are harder to seal well.
What's the difference between weatherstripping and caulk?
Weatherstripping seals parts that move, like door edges and operable sashes. Caulk seals cracks and gaps under about a quarter inch between parts that don't move, like the joint between a window frame and the siding.
I can see light under my door. Can you fix it?
Yes. A new door sweep or threshold seal closes the gap at the bottom. If the gap is wider at one corner, the door has sagged, and a quick door repair comes first so the new seal meets evenly.
Who weatherstrips old wood windows in Essex County, NJ?
Csiszer Property Maintenance, an insured handyman company serving Essex County and Union County, NJ. Seals are fitted to the sash edges and meeting rail and chosen so the window still opens and closes. If a sash is stuck or falls, window repair comes first.
Is it safe to make my house tighter?
Usually, but it's worth a check. The U.S. Department of Energy warns that sealing a home can affect indoor air and cause combustion appliances to backdraft. If you have a gas furnace, boiler or water heater, have a licensed HVAC contractor confirm the venting.
Do you remove old caulk in older homes?
Yes, with care. Some old window caulk and glazing compound can contain asbestos, so if there's any doubt, the material is tested before it's disturbed.
Can a landlord have every unit sealed before winter?
Yes. Share photos of the drafty doors and windows in each unit with the unit number, and everything is reviewed and quoted together. Photos of the finished seals can be shared for your records.
