About Us




How do I schedule an estimate?
Please call our office, 918.258.0012, or email us at  Residential and commercial estimates are free of charge.  Insurance and real estate estimates may incur a small, refundable quote fee.

My pool is in really bad shape, is it too far gone to restore?
In close to 30 years of business, we have just about seen it all.  Very, very rarely is a pool beyond the scope of restoration. 
Short answer, it's fine, we can make it happen.


Do I have to have the plaster, tile, and deck all done at the same time?
Absolutely not.  We will work with your schedule, budget, and desire to perform the work in a manner that best suits you.  It is usually best to get the tile work done before plastering, but not a necessity.  If you plan on doing all three, price breaks are available if all are done simultaneously.

Do you accept credit cards?
We do accept most major credit cards.  To account for bank processing fees, we add 5% to any invoice paid by credit card.

What are your payment terms?
We require 25% down prior to beginning any work.  The balance is collected once the work is complete.

How long does it take?
The answer to this has many variables.  A typical replaster with tile work is done in about 5 days.  Our schedules are very dependent upon weather.  Rain, wind, and temperature affect what we do.  As of yet we have made no headway in determining how to control the weather. 
Once we begin work on your job, we will not leave it until we are done.  Barring any outside influence (weather, client changes, etc.) we will stick with your job to completion.

Who will be at my house?
For the initial project review and quote, you can expect owner Greg McCourt.  Occassionally a homeowner is treated to an appearance by Jim McCourt to give an estimate.
For the project itself, it depends on what is being done.  All of our crews are led by foremen with decades of experience.  Most of the crews have been together for at least a few years.  We do not hire day labor.
'I will only send workmen to your house who I can trust.  The best example I can give is that if I don't trust them to be at my house when my wife and daughters are home alone, then they don't go to your house.' - Greg McCourt

You say you've been in business since 1984, but records for Marin, Inc. only go back to 2006.  Why is that?
Jim McCourt founded Mid Continent Epoxy in 1984.  In 2006 the epoxy portion of the business was sold along with the business name.  Jim incorporated the pool business under Marin.  So while the incorporated entity is still young, the experience and commitment we bring is strong.

Do you remove all of the old plaster?
For most remodels, this is not necessary.  Only if your plaster is coming off in chunks will we have to evaluate removal.  During our preparation we determine the soundness of the existing plaster.  As long as we have a solidly adhered surface to work with, we will leave it as-is. 

What if my pool is painted?
If your pool is painted and you want a plaster finish, the paint will have to be removed.  We generally do this by sandblasting the pool. 

What if my pool is cracked?
Most pools will experience hairline cracks that are insignificant.  Hopefully by the time you need your pool replastered, the tub will have settled completely in place.  These minor cracks will be plastered over.
Besides settling, ground movement, large tree roots, and large tree removal can have an impact on pool cracks.
If you have a moderate crack, it can be addressed at prep by patching.
Large, heaved cracks are structural in nature and will need to be assessed individually.
Any existing crack that is patched has a possibility of reappearing, dependent upon outside factors.

How long does it take to replaster?
If we are only replastering, the process takes about 4 days.  This does not account for weather delays or any additional work.  If you plan for 5-7 days you will not be disappointed.

How thick is the new plaster?
The new plaster is applied at 3/8" thick with adjustments made for uneven existing surfaces.

I can see the cement (gunite) showing through the plaster.  Is that bad?
This is a sign of excessive wear due to age or spall.  In small quantities it's nothing more than a rough eyesore.  Given enough exposed area, you can begin to notice water loss.  If this is left exposed for long periods, it can begin to erode the concrete shell of the swimming pool.

Why is my plaster rough?
This is the #1 reason for replastering a swimming pool.  Pitted plaster in older pools is a sign of age wear.  If you have a newer pool that is pitted, it is likely the water chemistry.  When the water is out of balance, it will pull minerals from the plaster to buffer itself, resulting in a rough finish. 
Rough plaster can also be the result of scale deposits.  This is a result of prolonged periods of high pH, Alkalinity, and Calcium.  The Calcium precipitates out of the water and deposits on your plaster.

Will new plaster help my algae problem?
To a degree.  New, smooth plaster will remove the rough surface area that gives algae a good foothold.  This will give you a boost in fighting the algae itself.

Do I have to replace my tile?
As long as your tile is in good shape it can remain in place for a replaster.  If tile is falling off, cracked, or sounds hollow when knocked on, there is a problem that needs to be addressed.

Why is some of my tile falling off?
Generally this is caused by deck movement creating a void behind the tile (see picture below).  It can also be caused by poor workmanship when the tile was installed.

Why does my tile sound hollow?
This will go hand-in-hand with buckled or failing tile.
Typically the pool beam (area of the pool on which the deck rests) is cracked or crumbling.  When we replace your tile, we will fix this.

Do I have to replace all of the tile?
If you only have a small section of failing tile we can usually replace it.  Hopefully you saved (or were left) some extra tiles from the pool build.  It is difficult to find matching tile that is more than 5 years old.  If a third or more of the tile is failing, you've come to a point where you might as well retile the entire pool.

Can you reuse my old tile?
Only in small amounts.  The labor costs add up quickly if you are paying us to clean each tile for reuse.

Can I change deck color?
Your existing deck color does not determine the color you use on a remodel.  You can change the deck color to any of our options.

What if my deck is painted?
If you deck is painted, we will have to remove all of the paint prior to applying Kool Deck.  We can apply our color sealant over most existing deck paints.

Can you patch Kool Deck?
Kool Deck can be patched, but it will be a noticeable patch.  Since Kool Deck is a hand applied product there is no consistent pattern to match.

How does Kool Deck compare to other overlays?
Kool Deck is cooler, less slippery, and requires less maintenance than other swimming pool deck overlays.

Can you fix the cracks?
Prior to overlay, we will patch over any existing cracks.  We cannot permanently fix a crack.  If the ground moves enough to move the concrete slab, it will crack through the overlay as well.  Extreme drought and rain will amplify any existing problem.

What can we do about the broken plastic control joints in our deck?
This is a common problem we address by removal of the plastic joint.  The seam is filled with a self levelling joint sealer.
